NEWGO Large Shoulder Ice Pack Rotator Cuff Cold Therapy Reusable Cold Pack Shoulder Ice Wrap for Shoulder Pain Relief, Recovery After Surgery, Swelling - Navy Blue

Excellent product. I was able to use this on my frozen shoulder injury. When I used this, I weighed close to 400 pounds. Fit well.

I originally ordered the large size. I had my wife measure my biceps with a fabric tape and it was 14". I'm not sure if the company mixed up millimeters and inches, but the strap around the biceps was so short (it's elastic) that when stretched enough to adhere to the Velcro, it was like a tourniquet. I ordered the x-large and it came today, and fits fine. If you are donning this by yourself, hook the velcro strap first and put it on like a sleeve. I was a Physical Therapist for 20 years but it was a long time ago. That said, here's some information about the physiology of using cold that might help. 1. The pack (ice pack inside the wrap) needs to be next to the skin for maximum effect. 2. 20 min is the effective time for the cold to do its thing. Longer won't make it more effective. 3. Initially, cold can cause achiness. We used to use chipped ice in a plastic trash bag and apply directly to skin. You might also experience some achiness and throbbing. Pain relief is at the end of this. These symptoms usually go away after the 3rd or so treatment, and my patients loved the ice once they were used to it. 4. Cold produces initial vasoconstriction (blood vessels get smaller in diameter). When you make snowballs, this looks like whitish skin. Then the body realizes this is dangerous for the skin and vasodilatation (blood vessels get bigger in diameter) occurs and floods the tissue with blood. This causes the redness. This is what helps healing. 5. Pain nerve fibers are type-C non-myelinated structures (electrical wires have insulation on them. Pain nerves are like bare wire) and are more susceptible to cold and heat. Cold slows down the nerve conduction velocity which results in decreased pain. Hope this helps. The pack is comfortable to wear. I found using a pillow to support my arm (sitting) helped.

I have a rotator cuff injury in my left shoulder. If you look at most of these ice packs on Amazon, they usually show it on the right shoulder. Because they make it easy to put on for the right shoulder but hard for you to put it on by yourself on your left shoulder! This particular unit is less difficult than some others I’ve bought. It doesn’t require trying to grab a strap behind your back. There is a short Velcro strap under the arm, but it’s relatively easy to reach. The negative is that it seems to have a smaller ice pack than some other units, even though it’s “large “. However it is much less painful to put on by yourself then some others. So if you have a left shoulder rotator cuff, and you have to put an ice pack on by yourself, this is a recommended purchase!

Fits well. Easy To adjust. Ice pad is designed to wrap your shoulder inside the device pocket. Stayed cold approximately 20min then cool for another 5. Much easier to use than balancing the usual square ice packs!

Very good quality with nice design.
