Dear MendMeShop,

I fell down on ice last March, hit my left shoulder on the ground pretty hard and stirred up an old injury that hadn't bothered me for twenty years. I was in a great deal of pain and tried everything I could think of that might help. I only found temporary relief from the pain. It wasn't until I began using your Shoulder Inferno Wrap that I truly began to heal and the pain slowly began to subside. After several months, I still use the Wrap daily to maintain the healing and progress I've made. I then also sought the advice of a physical therapist because in addition to the pain I used to have before using the Wrap, I was still dealing with stiffness and a very limited range of motion. After examining me, the therapist said I didn't have rotator cuff issues just muscle issues, a thing called "frozen shoulder". For seven weeks now I have received help from a massage therapist and am slowly improving the range of motion. I chose to work with her because her sessions include massage and stretching. A session leaves my shoulder feeling slightly sore. I use the Inferno Wrap afterwards and the heat I feel as it works relieves the soreness. I am sure using the Wrap also helps the muscles "remember" longer the right way they are supposed to feel and function. Combining the Wrap with massage therapy has been a winning combo for me! Do I dare confess...I love the Wrap so much that I will definitely buy another one. The Back Wrap will be my next purchase from you. I mean this whole-heartedly - thank you for the Wrap! I am also pleased with your customer service. Dealing with you was a pleasure. You really do care about your customers! I am delighted and impressed with your product and your people. __________________

Dear MendMeShop,

I have been using the Freeze Wraps to reduce the inflammation, for which they worked great. Last week was the first time I tried the Infernowrap on my right knee and it seems to help just from one treatment. I plan to use it every night when I get back from work. I used the knee Inferno wrap again last night and put it on the medium power and it's helping tremendously. I'm able to bend my knee better and walk with more stability without leaning too much on my left knee to compensate for the injured knee.

More Tendon Facts:

Inferno Wrap treatments can speed tendonitis recovery significantly.


A fully ruptured Tendon REQUIRES surgery. It will not heal on its own.


Except for a fully ruptured tendon, Tendonitis can almost always be cured without surgery.


Left untreated, tendonitis can be extremely debilitating and lead to life long complications.


Continually using your Tendon while it is injured will lead to a worse injury.

Dear MendMeShop,

I have nothing but good to say about the Inferno Wrap. I am continuing to use it daily. My shoulder is better than I imagined it could be in the amount of time I have been using it. Sometimes I go for days with no pain and when it does come back, it is no where near the intensity it was before the Inferno Wrap. Thank you so much for tracking my progress. A very happy customer, Louise Schiotis

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,

The shoulder Inferno wrap seemed to help me. I used it consistently after my shoulder had already been injured for several months, after receiving no real help from 2 visits to orthopedist. I feel that the wrap plus doing my own physical therapy at home and time helped. I'm so thankful My SHOULDER Is FINALLY healed!!!

Advanced Treatments & Therapies for Tendonitis

How to Use Superior Home Treatments to
Heal & Relieve Pain from Tendonitis!

 

The good news is that most cases of tendonitis will heal with simple home conservative treatments!

It's important to treat tendon injuries as soon as possible. Any activity or strain you put on your tendon can cause further damage to your weakened tissue. Though the pain, discomfort, and inconvenience of a tendon injury can be overwhelming, it's possible to overcome it with consistent treatment on a daily basis.

Start treatment of tendonitis as soon as you're injured!

Doctors, physical therapists and medical professionals all agree that the trick to any tendon injury is getting it to heal with minimal scar tissue formation and with as much realignment of tendon fibres as possible.

Even with optimum healing, there's always less elasticity in a previously injured tendon. This will cause the tendon to hurt during exercise and everyday activities. However, if you heal your injury efficiently and quickly with conservative treatment methods, your chance of re-injury later on is much lower.

Most doctors will recommend conservative treatment options to heal the torn tendon tissues as a minimally invasive approach. Other approaches (like surgery) are known to introduce even more scar tissue into your injury, and so this is why doctors will always recommend conservative treatment methods first as a "try everything" approach.

If you've suffered from tendonitis before you'll know that right now there are thousands of doctors and physical therapists helping people just like you to treat their tendonitis fast and heal the injury. If you want to remain proactive about properly addressing your tendonitis, speak to your doctor about adding to your conservative treatment with AidYourTendon's system utilizing BFST® and ColdCure Technology®.

Some conservative treatment methods recommended for tendonitis include:

  • Rest - This is important for initial healing because without proper rest you're at risk for increased pain, inflammation or even further tearing in your tendon tissue. This can make your tendonitis even worse and turn an acute injury into a chronic one.
  • Our Freezie Wraps provide consistent cold compression ideal for acute tendonitis injuries.
  • Avoid Activities that Caused Your Injury - While resting your injury it's also important to avoid all activities that may have caused your tendonitis (especially if you now have tendonitis from overuse or repetitive movements). Continuing on with regular activities will make your injury worse in the long run.
  • Apply Cold Compression - Immediate cold (using a Freezie Wrap®) will help you to manage pain while getting rid of the pain and inflammation. Immediate pain relief and reduced inflammation can also stop your injury from getting worse. A cold compression Freezie Wrap® offers consistent cold temperatures that WON'T reach temperatures so low it causes cryoburn on your skin (like ice or blue gel packs full of anti-freeze or chemicals).
  • Our Inferno Wraps provide Blood Flow Stimulation Therapy needed to improve blood flow circulation and speed up the healing process of acute tendonitis.
  • Use Blood Flow Stimulation Therapy - After any inflammation and/or swelling has been reduced, you can use your own blood flow to maximize healing of damaged tissue and maintain healthy blood flow to your sesamoid bones. This also boosts overall long-term healing of this injury. Treatment with an Inferno Wrap® also gives you deeply penetrating Blood Flow Stimulation Therapy (unlike other methods that just heat up the surface of your skin).
  • Avoid Over Compensating for your Injury on your "'Healthy' (Non-Injured) Side - Many people will start limping or carrying objects with their opposite arm to compensate for their tendon injury. Our bodies can adapt easily to any changes, including a tendonitis injury. This quick adaptation could mean that you're already compensating for your injury without even knowing it!

    When you compensate for your injury by using your opposite ('healthy') arm, leg, shoulder, knee, foot, etc. - then you are putting more weight and pressure on that side of your body. In many cases, your dominant side was injured (if you're right-handed this would be your right side) so your weaker side is trying to pick up the slack! The pain, stiffness, swelling and inflammation you then get on your 'healthy' side is something referred to as 'over-compensation pain'. Over-compensating for your injury can lead to other injuries and so that's why over compensation should be avoided at all costs OR treated with the same conservative treatment methods as your tendon injury.
If you suffer from a wrist injury you may also experience pain in your opposite (healthy) wrist, elbow and shoulder from compensating for your wrist tendonitis.

Use These Conservative Treatment Tools
to Deal with Scar Tissue

scar tissue restricts tissue fibers

It's important to rest the torn tendon because our natural healing process takes time to heal completely. If you don't rest your tendon injury, your acute tendinitis can quickly turn into a chronic tendinitis injury (tendinosis, tenosynovitis, calcific tendonitis, etc). To repair our damaged tendon tissue quickly, our bodies will use scar tissue to fill in the tears in the tendon. If you need to rest for an extended period of time and avoid certain activities that make your pain worse, you'll be more likely to develop massive amounts of this scar tissue as a temporary healing measure.

Scar tissue may plague you for weeks, months and maybe even years, depending on your level of activity and the amount of conservative treatments you have done during your rehabilitation. Scar tissue is a major problem, especially when it comes to re-injury of your tendon. When dealing with scar tissue it's always important to:

  • listen well to your physician and if conservative treatments are recommended, remember to stick to your (daily) treatment plan using these therapies.
  • frequent use of the Freezie Wrap® will help reduce the swelling very quickly. Much of the pain you feel will be from the swelling, and you'd be surprised how fast the pain drops off once the swelling is down.
  • the Inferno Wrap® is a safe, electromagnetic energy device that will help reduce scar tissue and increase blood flow to the area (thereby accelerating the body's own healing process).
  • when applied before stretching, the Inferno Wrap® will help flush the area with fresh blood. This will help improve your range of motion and prevent re-injury.

Allowing your tendon to rest is always recommended following injury. Avoid all activities that may have caused the injury or irritation and begin cold compression treatments as soon as possible. Then begin treatments with tools that can help treat your tendon and speed up the healing process so you can get back to a life without pain and risk of further injury. Blood Flow Stimulation Therapy will treat scar tissue and promote blood flow to heal your tendon faster and more completely than other methods available.

Other Conservative Treatment Methods can be Risky

Cortisone (Corticosteroid) Injections

Cortisone injections can be harmful to tendonitis injuries

Although steroid injections may provide temporary relief from the pain of tendon related injuries. They should generally be avoided as they weaken the tendon and may lead to a rupture. If you do opt for an injection, doctors usually recommend that you do not participate in strenuous activities for several weeks to reduce the risk of a rupture.

Doctors won't give you a cortisone shot if it's at all possible that you have a fracture (acute or chronic) in your sesamoid bone(s). If cortisone is used with even the slightest stress fracturing, the cortisone will make the injury worse by stopping the bone's natural healing process. Over time if left untreated, your fracture will get worse and surgery will be more likely needed.

"Medical evidence shows that cortisone shots can damage the surrounding tissue, fray the tendon, and even trigger a rupture. Most side effects are temporary, but skin weakening (atrophy) and lightening of the skin (depigmentation) can be permanent" (reference: American Academy of Orthopaedic Surgeons).

 


Treating Tendonitis - What You Can Do!


Usually conservative treatment methods are all that's needed to treat tendonitis. Other invasive approaches (like surgery) are only ever used if long-term conservative treatment methods don't work. If your Doctor has decided that your injury can be treated with conservative treatment options, then you'll find that many of our customers have had great success treating themselves with our powerful conservative treatment products - the Freezie Wrap® and Inferno Wrap®.

No one is immune to tendonitis, you can easily reduce your risk of further injury with consistent conservative treatments

 

Step 1 - Reduce Pain and Swelling with Cold Compression

The first step for conservative treatment of your tendon injury is to reduce the swelling to "open up" the area for more blood flow. Anyone in the health-care business knows that your blood supplies the oxygen and much needed nutrients required to heal tendon injuries. This is why for years, doctors, trainers, and other medical professionals have recommended RICE (Rest, Ice, Compression, Elevation) to treat the pain and swelling of fresh injuries, chronic pain, and after any re-injury.

Cold Compression Freezie Wrap Therapy for your tendon injury will reduce pain, swelling and tissue damage for faster healing.

Although RICE can help to treat these symptoms, ice and freezer gel packs reach temperatures so low they can cause cryoburn, an ice burn on your skin. The problem is, up until now there hasn't been any other option to treat painful conditions and injuries, so ice and blue gel packs (full of anti-freeze and chemicals) have been the only choice.

Fortunately you no longer have to settle for these ice cold methods that are uncomfortably cold against your skin, provide short term relief, cause ice burns, numb your skin and underlying tissue beyond feeling so you don't even notice the ice burn until it's too late and pool around your injury putting the cold everywhere except for where you need it most.

A Freezie Wrap® allows you to treat your tendon injury in an effective and convenient way. Our Freezie Wraps® will wrap around your body keeping the cold right over your injured tendon for the entire length of your treatment. Our food-grade, non-toxic gel packs can be chilled in the fridge or freezer to tailor the amount of cold that you need for your injury. It doesn't matter how you cool it down, because our gel packs are chock full of gel that's designed to cool down into millions of tiny snowflakes. This method of cooling means our gel packs aren't icy-cold! The cushioned gel will wrap around your injury and it won't budge for the entire treatment period. You'll no longer have to deal with the annoying pooling of gel around your injury or have to hold a hard block of ice on your body!

Cold Compression Therapy slows nerve and cell function - reducing the swelling that blocks blood vessels from doing their job.

 
Our Freezie Wraps provide consistent cold compression ideal for acute tendonitis injuries.

This is important because once blood vessels are blocked or damaged, they can no longer carry oxygenated blood through the tissue and tissue cells begin to break-down. Without cold compression therapy cellular break-down and tissue damage continues as the cells don't get the oxygen they need to survive. By limiting the amount of damage done to your tendon, you also limit the amount of healing that needs to occur. This is a very important step to heal tendon injuries faster and with less pain! This is why you need to treat your tendonitis right when you first notice the pain, when you have swelling / inflammation, or directly after a re-injury. Applying a Freezie Wrap® right away will stop the damage immediately and unblock your blood vessels to let your body's natural blood flow in to start healing the tissue.

Cold Compression Therapy = the Freezie Wrap®

 

It'll seem weird for you to read this, but there are a LOT of people out there that don't understand how fast cold compression with a Freezie Wrap® can get the swelling / inflammation from your tendonitis under control! After you get rid of the swelling for good you can start dealing with your tendon injury and pain head on.

Use a Cold Compression Freezie Wrap®:

  • 24 to 72 hours after your initial tendon injury or when you first notice pain and swelling to stop cellular damage, relieve pain, and decrease swelling.
  • After exercise, workouts or activity of any kind to prevent re-injury of your tendonitis.
  • Before and after surgery during rehabilitation to control pre and post-surgery pain and swelling.
  • Anytime you feel your tendon tissue is tender, painful or you're having a flare-up of an old tendonitis injury.
  • Anytime you have swelling, sharp throbbing pain or inflammation.
  • Any other situation where you need to draw the pain and inflammation out of your injury.
 


Step 2 - Improve Circulation, Soften Scar Tissue & Prevent Re-Injury with Blood Flow Stimulation Therapy

After the inflammation around your injured tendon has been reduced, you need to provide extra blood flow to strengthen your tendon tissue.

healing your ankle tendonitis

Promoting blood flow to your tendon to help your body heal itself is a concept that has been utilized for centuries. Oxygen and nutrients, carried within the blood, are critical for the body to heal itself. Without proper blood flow, your recovery from any soft tissue injury will be delayed... sometimes for a very long period of time.

Even though the concept is simple, improving blood flow to your tendon while it's injured can be difficult. Traditional methods require you to move in order to promote blood flow - but that same motion that promotes blood flow can also make your pain and tendon injury much worse. Relying on movement alone to increase blood flow puts you in danger of re-injuring your tendon.

So what do you do when you need to increase blood flow, but you can't move without re-injuring your tendon?

That's where Blood Flow Stimulation Therapy (BFST®) comes in! Using BFST®, will help with your recovery and heal your tendon more completely. BFST® increases the amount of blood that flows naturally to your soft tissue to nourish your tendons, improving elasticity and speed up the healing process. This increased Blood Flow Stimulation Therapy to your injured tendon is greatly needed.

MendMeShop Inferno Wrap speeds the healing of tendon injuries and tears

The only way to get BFST® is through use of an Inferno Wrap®. The Inferno Wrap® is the only treatment method that improves blood flow and circulation on a deep tissue level. Other methods of warming up tissue (hot water bottles, hot baths, etc) will only ever increase blood flow on a surface / skin level. These methods need a LOT of time to even reach your tendons on a deep tissue level. And even if you were to use them this long your skin would heat up to an uncomfortable level and you might even get burned!

The best source of blood flow circulation treatment is from a product where you don't even feel that much heat. When you don't feel the heat, it means the therapy is working in your deep soft tissue which is really where you need it. It's kind of like how your heart works in your body. You can't "feel" your heart pumping blood all around your body to your arms and legs. You can't even hear your own heartbeat without listening very closely. This is exactly how deep tissue BFST® works too! You're not supposed to "feel" a lot of heat because the heat isn't treating your skin, it's treating your injury increasing the blood flow right in your tendon tissue.

  • When treating tendonitis or any soft tissue injury, an effective therapy will increase blood flow to the injury while the joint is immobile.
  • This increase in blood flow will accelerate the body's own ability to heal itself.
  • The Inferno Wrap® is the most highly effective blood flow stimulation device that you will find on the market that is approved by the FDA for use in the home or hospital.
Our Inferno Wraps provide Blood Flow Stimulation Therapy needed to improve blood flow circulation and speed up the healing process of acute tendonitis.

Our Inferno Wraps® are made from medical-grade material - this should be as important to you as it is to us! Other products that are sold in stores are considered "consumer goods" meaning the material only needs to be as good as a sweater that you wear. Clothing articles like this don't need to meet high standards of production or materials and may include materials that irritate your skin.

Since our wraps are medical-grade products registered with the FDA, they are of a higher quality and need to meet way more standards for manufacturing (ISO 10993 - bio-compatibility testing). This makes our wraps the best consumer product for BFST®. Our manufacturer has spent years perfecting the wrap design to make sure you get the treatment you deserve!

Use BFST® Inferno Wraps®:

  • After swelling and inflammation have been reduced with cold compression.
  • Before exercise or workouts to warm up your tendon to prevent re-injury.
  • Before and after surgery during rehabilitation to warm up your tissues before physical therapy exercising or stretching.
  • Anytime you feel your tendon has stiffened up, is tight and your mobility is reduced causing you more pain.
  • Anytime you have sore or aching tissue.
  • Any other situation where you need to increase blood flow to relax your tendon, relieve pain, prevent re-injury and enhance flexibility.
 



It may seem hard to believe, but our Freezie Wraps® and Inferno Wraps® will assist you in recovering from your injury faster and reduce the chance suffering from degeneration conditions (like arthritis or tendinitis) by maximizing blood flow where it's needed most and reducing swelling / inflammation induced pain.

Tendon Injury Facts:

When the tendon gets inflamed it is known as tendonitis, and when the tendons are chronically overused, it may lead to microscopic tears in the collagen matrix and causes a gradual weakening of the tissues.


Achilles tendonitis is a common injury among runners, as the Achilles tendon is responsible for helping you lift off the ground with each stride.


As computers become ever more important elements of the work place and everyday life, incidents of wrist tendonitis are on the rise.


Oral Medications can mask the pain but do not aid in the healing of tendonitis. Anti-inflammatories and pain killers can mask the pain and indirectly cause tendonitis to worsen.


Ice and Compression treatments are the easiest and most effective treatments for tendonitis.
