ok more questions.

The likelihood of this is one in a million....but I'll ask anyway. Can a nerve be entrapped in a muscle?

my biceps (both, that's why I feel it's so unlikely) feel like they have a cramp in the middle. then from that point and down my arms burn, tingle, prickle, twitch etc etc. my biceps feel sore and it feels good while I massage them (then burn later). Could I have a nerve trapped there? It's like there are these invisible lines on my arms (and legs) that mark the start of the horrible feelings.
