“Feels good I bought this because I broke my wrist, resulting in a titanium plate that hooks into the bone as well as seven pins and four screws. Ouch! I started OT two weeks after surgery. It hurts, and there's still quite a lot of swelling. The OT recommended this sort of gel pack with gel beads because it would conform to my hand and arm, and it can be heated to help relax the muscles and tendons or cooled to reduce swelling. I do wish this was offered in a medium size, though. I have smaller ones that I can sandwich on either side of my hand, but they're too small to cover my wrist and forearm. This one is big enough to cover your whole back, which makes it almost twice the size I need. That means it's heavier and difficult for me to evenly distribute the beads (which have to be squished around, since they heat unevenly in the microwave). Still, it can be done--it's not ideal, but it's better than the ones that are much too small.”
