If I'm very active in doing something, say mig welding for 10 or so hours, my hands will be sore for a couple days. Weird sore. I went to the doctor and they tryed to give me some pills for when they are sore. Is a perscription the cure-all nowadays? I declined the drugs and just deal with it. But i cannot say that it has ever woke me up at night. Usually for the next couple days after, I have no grip. I probably could not even hold myself up on the monkey bars at the local playground LOL, or even grip a wrench. But it goes away eventually..till the next time..
Let us know what you find out. Miserable thing to deal with man.
