I have permanent nerve damage in my shoulder area to one side. Can't do much for it, and normally it doesn't bother me. The best medicine has been keeping my weight where it should be. Same goes for another part of my body that suffered damage sometime ago. If I gain more than 5-10 pounds, the pain begins to flare up. Lose it, and it goes away. Funny how these idiots can't work out two and two.
