There are many serious problems on this site. I have just a little suggestion for the possible alleviation of peripheral nerve pain in the legs: A good half-hour before I go to bed I put my cold-gel pillow insert (from Robert Dyas) in the freezer. It helps to settle the nerves while I read and then am able to drop off. A folded hand-towel might also be tried.
Doesn't work for cramp though - OW! - which can even wake me up, any tips?
