Since what you want is a theoretical answer, then I'll repeat what I've been told. Yes, theoretically, nerve pain from a compression will resolve in time after the compression is removed. Nerves regenerate very slowly, so amount of damage = amount of regeneration time. What I know for a fact is that post-damaged nerves aren't the same as pre-damaged ones. Things can get a bit wonky, for lack of better word. I have spots along a regenerated nerve that I cannot feel, and even weirder, I can touch point A but feel it in part B. Small price to pay of course, but I did want to mention it.
