t night we were at an educational meeting with our Chiropractor last night and learned that even the weight of a quarter placed on your palm for 3 hours can cause nerve DAMAGE.

That seems very, very unlikely to me. I've held far more weight than that for far longer than that, without injury.

My suggestion is that you ask a doctor. Not a chiropractor, a doctor. Preferably a neurologist, but if you don't have access to one, start with your GP, and get him to research it.
