More Hamstring Injury Facts:

Oral Medications can mask the pain but do not aid in the healing of a Hamstring muscle injury. Anti-inflammatories and Pain killers can cause Hamstring muscle related injuries to worsen.

One out of three athletes who sustain an initial hamstring injury will reinjure their hamstring within a year of returning to play. It is theorized that weakness in the hamstring muscle due to incomplete or improper (scar tissue) healing will often cause a hamstring re-injury.

A Grade 1 Hamstring Injury is a mild strain with a few torn muscle fibers in the hamstring.

A Grade 2 Hamstring Injury is a moderate strain and the patient shows a definite loss in strength.

A Grade 3 Hamstring Injury is a complete tear of the hamstring muscles.

10% to 23% of all acute soccer injuries are typically hamstring tears and hamstring strains (also known as strain injuries of the posterior thigh).

A complete tear of the Hamstring will require reattachment surgery. There is no avoidance of this.

Dear MendMeShop,

I use both the Inferno and cold packs and they are fantastic. I run 3 to 4 triathlons each year and these products have help treat my severe tendonitis in my leg. The only downside is that they don't remind me to use them as often as I should:)

Dear MendMeShop,

I purchased the Inferno wrap and Freezie wrap to treat a chronic Achilles tendonosis (MICROSCOPIC TEARS OF THE TENDON AT THE INSERTION). During the later part of 2008 I was experiencing a lot of tight muscle and tendons and usually working out (running) tired and not properly warmed up and limber. I started the new year with good intention and determined to work on stretching that included following a home yoga program. I am familiar with yoga but admit that I was too aggressive with the stretching that comes from the 'downward dog' position. I believe this aggravated an already existing condition in the Achilles insertion area, this combined with the stress of a late January 5KM road race caused enough pain in the Achilles tendon to force me to discontinue running. I sought medical attention from my family physician who referred me to physiotherapy. Through the early stage of therapy I continued to do regular bike workouts. Unfortunately the pain increased to the point that I had to stop both running and cycling. I attended physiotherapy for just over two months going once a week receiving massage to the injured area, ultrasound, cortisone by patch and ice. I was religious in following the gentle stretching and strengthening routine at home between physio visits. After these two months with little improvement they released me with the instruction to continue with the stretching, strength exercises and ice. I was still in pain and could not run or cycle without causing further damage, walking was painful. I search for other solutions and found the information on the MendMeShop web site. Although skeptical, I purchased the wraps out of desperation, received the product, read all the literature for use and started into a daily routine. Within 7 days I started to experience a reduction in the constant pain. Within 9 days I was walking without a constant reminder of the injury. I tried doing a ride and although the short 13 mile ride was enjoyable I started to feel the injury flair up again. The injury is not completely healed but the progress I am experiencing gives me hope that with a continued discipline of home treatment using the products, gentle stretching and the use of wearing a brace on my foot while sleeping to prevent the tendon from retracting, will in time bring about the full healthy healing of the injured area. I have found that you really have to be in tune with what you are feeling during the gentle stretching and often back off the stretch so as not to cause repetitive injury to the already weakened area of the Achilles insertion.

Dear MendMeShop,

I'm doing well with my Inferno Wraps. I have one for my foot, leg, back, and elbow. My elbow IS gradually getting better. The foot/ankle/Achilles, leg, and back/hip are helping a lot. I have a complex soft tissue injury from a fall where my foot was asleep and I did not know it ... UNTIL I fell on the floor, having twisted (running on my foot that turned over) my ankle, knee, and hip. I have healed well from the original injury (now 4 years ago) with lots of chiropractic and massage therapy and lots of rehab. One of my rehabs now is "Ballroom Dancing" with a teacher who understands injuries. I call it "Physio-dance therapy for rehabilitation." I've done this for the last 8 months and have gotten incredibly stronger and improved coordination and balance. But, 3 weeks ago I "strained" my Achilles/calf/ankle/foot muscles and tendons. I purchased the Inferno Wraps to help expedite my healing, which they HAVE DONE and I've only used them 2 weeks now. I am using them 2 times per day, every day.

Dear MendMeShop,

I'm regularly using both Leg and Plantar Inferno Wraps now and I'm already seeing extreme/good results. Basically I'm doing lots of running now and enjoy competing 5k's & 10k's. Hopefully full marathon soon and to achieve better results I need to train hard; consequences [of this] are typical running injuries. Obviously I'm treating my Plantar Fascia [with the Plantar Inferno Wrap], and using the Leg Inferno Wrap I'm treating my calf and hamstring. Both Inferno Wraps I should say are user friendly / easy to use except you need to be near electrical outlet to operate this gadget. I should say this equipment is a big help to the runners world.

Possible Reasons for High Rates of Hamstring Injury:

Timing and Coordination problems during a running sprint - specifically during the time the back leg is off the ground and pulled forward (to place on ground in front of you).

Running stride is too long (overstride), or the sway in the run is significant (causing more stress on the hamstring).

An Improperly healed hamstring injury will predispose you to another hamstring injury.

Lack of stiffness in the hamstring muscle will increase your chance of a strain when your feet are contacting the ground in a run. (inability to absorb enough shock)

Improper warm-up before exercise.

A slippery playing surface increase your odds of a hamstring strain due to slipping.

Certain Lower Back Issues may potentially cause weakened muscles; weak hamstring muscles are more prone to strain than stronger hamstring muscles.

The Passive Hamstring & Calf Stretch Device:
The Final Step in Upper and Lower Leg Muscle Rehabilitative Therapy

This Device is Currently Used in Hundreds of Physical Therapy Clinics and Hospitals in Canada - This Same Device is Now Currently Available for Use at Home

Stretch your muscles to boost healing.

It's now possible to boost your healing by stretching your hamstring injury at home. Stretching is the final step needed when healing your hamstring muscle injury (sprain, strain, pull, spasm) with conservative treatment methods.

Your body is capable of healing itself - and natural healing will happen even faster by using consistent conservative treatment with a Therapeutic Cold Compression Freezie Wrap®, Blood Flow Stimulation Therapy Inferno Wrap® and Passive Muscle Stretching / Strengthening with a Knee-Flex®.

Knee-Flex® = a Passive Muscle Stretching Device Used in Hundreds of PT Clinics and Hospitals in Canada

This Same Device is Now Available for Use at Home

Knee - Flex Therapy Usage

This seemingly simple device has assisted in the recovery of thousands of patients that have suffered many various injuries. Once a patient is on the path to healing, this device assists the patient in making a fast and full recovery.

The Knee-Flex® Passive Knee Stretch Device assists in complete and full recovery for:

  • Patients recovering from surgery (ie. hamstring reattachment, quadricep reattachment, knee replacement, lathroscopic knee and hip surgery, debridement).
  • Patients recovering from a serious thigh muscle injury
  • Patients recovering from a serious Hip Injury such as Illiotibial Band Syndrome or Acetabular Labral Tear
  • Patients recovering from Hamstring Pulls, Hamstring Strain, Calf Pulls, Calf Strains
  • Patients recovering from knee or hip dislocations
  • Patients recovering from Achilles Pulls, Achilles Strain, Partial Achilles Tears, Achilles Post-Surgery Rehab

For many people, stretching seems like such a basic thing... They wonder how stretching can really help a hamstring injury. You would be surprised by how many people there are that don't understand the importance of stretching a deep tissue muscle injury.

knee flex is better than heel slides

Before making the transition to crutches, physical therapists prescribe gentle stretching of an injured hamstring, and if no device is available, they usually prescribe heel slides. They don't prescribe this to annoy you - it is in fact the most important part of knee injury recovery. You probably know of someone that chose not to do these stretches as it is common and they paid a high price for it. By not listening to the therapist (ie. not stretching), there is a huge chance of re-injuring your hamstring or even sustaining an injury greater than the original injury ever was.

The Knee-Flex® was created to allow the heel to slide smoothly in a controlled environment, minimizing the chance reinjury and additional pain. Physical Therapists encounter the same issues every day when attempting to work with patients who are undergoing therapy from a serious thigh, hip or hamstring muscle injury. This is why most therapists in Canada instantly purchased these same devices for their own clinics. For patients recovering from serious pain, it allows a more controlled and comfortable method to stretch and strengthen the muscles and ligaments in both the hip and knee joint. The sliding mechanism is extremely smooth and durable, as well as linear - something that becomes very important in such cases.

It may seem hard to believe but it's true - Stretching is the secret of healing any muscle injury. Consistent stretching is one of the only solutions to break up scar tissue that forms on your muscle as it heals.

Stretching with ColdCure Technology® and BFST® is even better!

Using the Knee-Flex® Deep Tissue Muscle Stretching & Rehabilitation Device not only helps minimize the growth of scar tissue, but it also increases the elasticity and strength of the joint. After using the Knee-Flex® over time, your hamstring (or quad) muscles will be better prepared to handle higher and higher loads. Eventually you will reach a stage where your injured leg can handle crutches or standing for longer and longer period of time. This is the final stage of recovery and depending on age, the nature of the injury, your weight and many other factors, it can take the longest time to complete. Remember for upper leg, hip and knee injuries, it pays to be patient! Rushing your injury recovery almost never pays.

Combining Freezie Wrap® cold compression therapy, Inferno Wrap® BFST® therapy and the Knee-Flex® allows you to effectively treat knee, hip, thigh injuries with the most effective home treatments that are available.

Stretching = The Best Way to Deal with Scar Tissue

Scar tissue will grow in to protect your injured muscle, but the scar tissue will attach to everything resulting in a hard fusing together of tendon tissue - reducing mobility.

Even when you're injured and in pain you need to keep moving to break up scar tissue that's forming in your muscle. Regular movement can increase healthy range of motion (ROM) of your muscle, resulting in a speedier recovery process and return to regular activities. Moving when you're injured is hard. Since moving while injured can be painful - most people think it's better to stop moving, rest their body and hope that their muscle strain will heal all on its' own. Even though rest is important to recovery too much rest during the recovery process will increase the amount of scar tissue on your muscle.

During the healing process your body will fill in tears in your muscle with dense, brittle tissue called "scar tissue". The human body will use scar tissue as a temporary solution and will try to build the scar tissue as fast as possible to heal a tear. Scar tissue can form fast to bring together the edges of a tear, but working fast doesn't mean that the job's done right. When scar tissue forms it doesn't come together as neatly as regular (healthy) muscle tissue would. Scar tissue fibers will lay down over top of your tear in a cluttered, messy and jumbled up way.

Imagine throwing a bunch of drinking straws in the air... Those straws will land in a random, unorganized way. It seems silly to think that those straws could land perfectly straight and all in the same direction.

This is how scar tissue works. The scar tissue that forms on your muscle will be unorganized and won't line up properly with the healthy tissue surrounding the tear. This scar tissue will also attach to everything in and around your muscle including the surrounding healthy tissue as well. This can result in a long-term fusing together of your muscle that stiffens up your tissue, reducing your mobility and making your injury even more painful!

Scar tissue builds on the muscle as the tears heal. The build up causes pain and inflexibility making your muscle more prone to further injury.

This is why scar tissue is weak and only a temporary solution to heal your pulled / strained muscle. Scar tissue is something that needs to be dealt with fast. If you try to get back into your regular daily activities with a mound of scar tissue on your muscle you'll have a higher risk of re-injury. Scar tissue is just not built to withstand the pressures of regular activity.

If you have an injured muscle with a lot of scar tissue and re-injure that tissue, even more scar tissue will grow to fill in those tears. If you keep falling into the dangerous cycle of re-injuring your muscle without proper treatment you could end up with massive amounts of scar tissue. Your ability to move your affected muscle in a normal way will be impaired as the amount of scar tissue increases.

The only solution to truly repair your pulled muscle for good is to break up scar tissue and avoid re-injury.


This can easily be achieved with regular use of the Knee-Flex®. This device provides a sturdy hardwood track with an easy gliding motion giving you the same stretch everytime. Your movement is controlled reducing your risk of re-injury. The result is a consistent stretch that helps to break down your scar tissue and improve flexibility in your muscle.

Use the Knee-Flex® to Bring Your Deep Tissue Muscle Stretching & Rehabilitation
to a Whole New Level!

It's very common for a physical therapist to combine conservative treatments and stretching techniques to help you heal your strained muscle. They'll also probably give you advice to continue specific stretches at home, everyday, to increase your rate of recovery. If no device is available to allow for consistent stretching of your muscle at home the physical therapist will usually prescribe something called "heel slides".

Heel slide movement without a device like the Knee-Flex often results in uncontrolled, inconsistent movement that could lead to further injury of your muscle.

A "heel slide" is a full flex and extension of your lower leg. Heel slides can be performed in a seated or laying down position. To start this movement you first need to slide your heel in toward your body, then you slide it right back out away from your body.

Heel slides (full heel to hip movement) is nothing new... Common stretching practices like Pilates, Yoga and other fitness techniques all encourage heel to hip movement to firm, tone and condition the muscles and soft tissue in your lower leg, thigh and hamstring. This movement is also used to increase alignment of your leg from your heel to your hip and improve your lower body balance. A lot of muscle, tendon and ligament groups are involved in this stretch - like your hip (hip flexors), hamstring muscle, quadriceps muscle, your groin, all of the tendons and ligaments in your knee, your calf muscles, your shins, and your ankles. This is why heel slides are considered to be a foundation stretch for ALL of your leg muscles.

When physical therapists perform heel to hip stretching they'll manually flex and extend your leg for you until you have enough strength to do it on your own.

You'll slowly get the hang of this movement in physical therapy and your therapist will recommend that you continue a set of heel slide stretches several times each day in your own home.

Physical therapists will manually manipulate your leg to perform assisted heel slides while massaging different areas of your leg.

When trying to do this stretch on your own your physical therapist might encourage you to use household tools to assist in your stretch.

They may suggest you use:

  1. a plastic bag,
  2. cookie sheet,
  3. a tension band,
  4. a belt,
  5. or some other tool to help you slide your heel away from your body.
The Knee-Flex provides easy, consistent heel slide stretching and is exclusively offered by

They recommend these tools to help you get consistent stretching and assistance during your stretching routine. The problem with this is that using a plastic bag or cookie sheet during this stretch can be unsafe, with little to no control over your lower leg... Potentially resulting in an even worse injury!

This is where the Knee-Flex® comes in! The Knee-Flex® provides safe, consistent, controlled leg movement on a sturdy, hardwood track. This makes sure that your heel slides are the same every time!

Your stretch won't vary or change as you attempt a higher number of repititions, experience set-backs from re-injury, or lose control over unsafe household tools.

What if You've Never Gone to a Physical Therapist?

Knee-Flex is used throughout Canadian physical therapy clinics and hospitals.

The idea behind the Knee-Flex® is exactly the same. If you're someone who hasn't had the chance to see a physical therapist you might think that stretching is hard to do without guidance from a medical professional.

In some ways you're right - Without the direct guidance of a physical therapist it's easy to make mistakes when stretching at home. You may have even attempted some stretching you saw in a pamphlet/brochure in a doctor's office, or searched online for muscle stretching techniques. If you try this on your own there is always a risk of re-injuring your muscle.

You can get the same positive results of stretching in physical therapy appointments by using a Knee-Flex® in the comfort of your own home.

This is the final stage of recovery, depending on your age, the nature of your injury, your weight and many other factors, it can take the longest time to complete.

But remember, when it comes to deep tissue muscle injuries - it pays to be patient! Rushing your injury recovery almost never pays.

There is a Unique Formula used for Recovery from Hamstring Pain...

We're going to let you in on a key piece of information... In every physical therapy appointment your physical therapist will use conservative treatments, massage, manual manipulation and/or stretching exercises to give you this Professional 3-Step Treatment Formula:

Step 1 - Warm Up Your Hamstring

Physical therapists will warm up your muscle by performing deep tissue massage.

For this 1st step many physical therapists will use heat, manual manipulation, deep tissue massage, clinical ultrasound devices or a warm bath to warm up your muscle. The goal during this first step is to increase healthy blood flow circulation and relax your affected muscle.

'Warming up' your muscle will increase the elastic-nature of your muscle fibers making it much easier to stretch and when needed, hold the stretch. This will also extend the amount that you will be able to stretch your muscle.

Increase Your Blood Flow Circulation at Home

The Perfect BFST Leg Wrap

Use an Inferno Wrap® for 15 to 20 minutes at least half an hour before stretching your muscle. An Inferno Wrap® will promote Blood Flow Stimulation Therapy (BFST®) - a therapy that will increase the blood flow to your muscle while warming up and relaxing your injured tissue. BFST® will make your muscle fibers more elastic and pliable, allowing for more ease of movement when you're stretching and/or exercising.

Continued treatment with BFST® will also deliver much-needed oxygen, nutrients, antibodies and energy to your muscle. This will boost your own natural healing ability and speed up your time for recovery.

Step 2 - Stretch Your Hamstring

After your muscle is warmed up your physical therapist will guide you through stretches to improve mobility.

The main goal of physical therapy is to exercise (stretch out) the affected muscle from your injury, also to improve flexibility and range of motion. After the physical therapist has warmed up your muscle, they'll get you to do a series of exercises that are focused on stretching out your muscle.

This exercise may include heel slides that are focused on moving your quadriceps, groin, hip, hamstring, calf and shin.

Sometimes cardiovascular exercise, like using a stationary bike or treadmill, will be recommended under the supervision of your physical therapist.

Improve Your Hamstring and Leg's Range of Motion at Home

The Knee-Flex® can be used to perform consistent stretching that's beneficial to all of the muscle groups in your leg. Start off with 10 repititions of the Knee-Flex® stretch at least once everyday. Increase your repititions as the movement becomes more fluid and natural for you.

Amazing Hamstring Stretching with Knee-Flex

You can easily modify these stretches to further work out specific muscle groups in your leg by turning your foot in toward your other leg (point your toe in) when sliding your leg out away from your body, then turning your foot out away from your body (point your toe out to the side) when sliding your leg in toward your hips/lower back.

Another subtle change to this movement is pointing your toe forward when sliding your heel out, away from your body. You can then flex your foot up (pointing your toe to the cieling) when flexing your knee and bringing your heel back toward your body.

These small changes in movement will boost the amount of work all of the muscles in your legs are doing while using the Knee-Flex®.

Step 3 - Cool Down Your Hamstrings

Toward the end of your appointment your physical therapist may introduce cold compression, acupuncture, or TENS to relax your hamstring muscle(s) after the intense stretching and exercise.

Relieve Your Hamstring Muscle Pain & Swelling at Home

Sprained Hamstring Cold Compression Treatment

Use a Freezie Wrap® after using your Knee-Flex®, stretching / exercising your hamstring, or whenever you feel deep tissue muscle pain. The Freezie Wrap® will relieve any on-going pain and swelling while preventing full-blown inflammation from returning after your stretching.

Start with a 20 minute treatment directly after activity and apply more cold compression whenever you need to relieve pain and inflammation in your hamstring.

Each Freezie Wrap® has non-migrating RigiGel® that keeps the cold over your hamstring where it's needed most. With 3 extra large gel packs you also have the ability to swap out gel packs to extend your post-stretch cool down however long you need it.

Get Even More Healing Potential
from Your Knee-Flex®

Regular stretching with a Knee-Flex® will also give you:

  • Chronic Hamstring Pain Recovery & Post-Surgery Rehabilitation in the Comfort of Your Own Home

Our Knee-Flex Passive Hamstring Strething Device will increase flexibility of your healing tissue and help to break up scar tissue that forms on your muscle.

After you've injured / pulled / strained / sprained your hamstring muscle(s) massive amounts of scar tissue will grow all around the micro-tears in your hamstring to provide a "temporary fix" and increase stability of your hamstring. Scar tissue will constantly grow when you're suffering from a chronic hamstring muscle injury and even when you're recovering from open or arthroscopic surgery.

Scar tissue causing your hamstring muscle fibers to stiffen up over time. This is why your hamstring will feel less and less flexible and where your tightness will come from.

The only solution to get rid of scar tissue and promote growth of healthy, flexible tissue is repeated motion through exercise. The Knee-Flex® will provide natural, fluid, passive stretches that will stretch out the scar tissue increasing the flexibility of your hamstring and improving overall range of motion (ROM).

  • You get the Same Benefits Available with any Orthopaedic & Physical Therapy Rehabilitation Program

You'll find that regular lower leg stretching and conservative treatment with any rehabilitation plan will help to:

  • build muscle strength in your hip, thigh, quadriceps, hamstring, calf and shins
  • increase mobility and range of motion (ROM)
  • speed overall healing
  • prevent muscle loss (atrophy)
  • improve muscular function and capability
  • refine muscle fiber tissue alignment and physical balance
  • encourage overall muscle deep tissue flexibility
  • provide a proper warm up for regular exercise
  • promote healthy circulation in your hamstring

Using Your Knee-Flex® - Helpful Tips & Tricks

The Knee-Flex® will become an invaluable tool in your recovery. When used correctly, this device can strengthen and stretch four different muscle groups and stimulate blood flow in your soft tissue for a speedier recovery.

Speak to your doctor and/or physical therapist about using the Knee-Flex® device for your rehab exercise. Here are a few things to consider when you start using it:

  • On the 1st session, loop a belt or bathrobe around your foot to assist your efforts. Once you find this is not needed then stop using the loop.
  • Don't worry if you're unable to perform a full stretch when first using this device. Do whatever stretch you can and this machine will assist in increasing your range of motion over the long run.
  • Our Knee-Flex Passive Muscle Strething Device will increase flexibility of your healing tissue and help to break up scar tissue that forms on your muscle.
  • Set up the machine in a stable area free from obstruction. Most of our users find a pillow is very helpful as well for sitting/lying on.
  • Always use the machine slowly and in a controlled manner. Quick, jerky movements are not helpful and will only cause added problems.
  • When placing your heel on and off the machine, use your arms to lift your leg. This will keep the stress off of your injured muscle.
  • Always follow the instruction manual provided with your Knee-Flex®.

Hamstring Injury Facts:

Hamstring Muscles cross both your hip and knee, and help extend (straighten) the hip or bend the knee.

A Hamstring injury is an injury to one of the three different hamstring muscles in the back of the thigh.

The three Hamstring muscles name are: Biceps Femoris, Semitendinousus, Semimembranosus muscles.

Continually using your Hamstring muscles while injured will lead to a worse injury; and yes, it is difficult to avoid using the Hamstring.

Most Hamstring injuries happen while playing sports, such as soccer or football.

Once you have suffered one Hamstring injury, there is a very good chance you will suffer another Hamstring injury.

Dear MendMeShop,

Hi Paul. I thank you for your personal follow up. I have bought several of your products and I will tell you right now the Inferno Wraps are the BEST. I was in a walking boot last December for what was diagnosed as moderately severe tendonosis. Surgery was recommended. Instead I gave it time and started using the Freezie Wrap and the Inferno Wrap. After consistent and continued use of the Inferno Wrap I am 100% good to go! Your products are the best! Walker S

Dear MendMeShop,

I have been using the Inferno & Freezie Wraps since November,2012. I saw an orthopedic doctor after Thanksgiving and have been going to occupational therapy (3) days per week. I was told by my ortho doctor to continue to use the items that I had purchased from you (I brought them in on my initial visit with him). I am currently using the inferno wrap as soon as I wake up in the morning, then continue to do my daily wrist and arm exercises. I use the freezie wrap when I am finished. While working I use a tennis elbow brace and I am also using it while doing housework or other chores where I am using my arm alot. My arm is improving slowly as I am working (4) days a week as a chef for 12-14 hours per day. My ortho doctor told me that it would take some time to heal completely. I don't see him until the end of February (3 months since initial visit). So far I am seeing improvement in both pain management and flexibility. I believe the combination of therapy sessions and the use of your wrap treatments are the key to a successful treatment plan. I'll keep you informed of my progress. Thanks again for your help and guidance.

Dear MendMeShop,

Paul, The things I ordered from you seem to help and I am glad to have them. It has been really hot weather here so I don't use it as often as I should but it has relaxed the shoulder and I have a lot more movement. Thanks for your help, you speak the truth. I am telling others of your products.

Dear MendMeShop,

I have only used the inferno heat wrap for about 2 weeks for a fairly significant achilles tendon problem that has plagued me for several months. A recent MRI shows partial tears and an irregular shape to part of the tendon. It seems to me I am getting amazing results already from use of the products I purchased. I am back to playing tennis on a limited basis and realize I need to show restraint but it certainly appears I am on the mend. I am extremely impressed by the professionalism of your company and the personnel that I have talked to in the ordering process.

Dear MendMeShop,

I constantly use the Leg Inferno Wrap for my thigh and hamstring walking/running. It's great for shin splints.... feels good when muscle gets hot. Really helped when I woke up one morning with a lower leg deep vein Thrombosis really bed with the combo of whey protein; herbs for inflammation; and wearing this I was able to start running again in three weeks and walk normally in 2 weeks. Constantly use every evening and feels good after; For anyone like me it's a great product.

Dear MendMeShop,

I recently ordered the Inferno Wrap and wanted to tell you how great it worked. I had a minor MCL tear and bursitis of the knee from a fall on ice in February, yes here in the Southern US, we do have ice sometimes and we don't know how to walk on it. Well, to make a long story short, I healed much faster and will recommend your product to others. Also, a representative from Mendmeshop called and asked how the product was working. This is unheard of in today's world. I never realized how long or involved a knee injury could be. Thank you for such a wonderful product.
