What could be wrong with my arm?

[sconeonamission]

possibly the carpal tunnel, maybe its pressing on another nerve?

Could it be possible that you had a really minor stress fracture that was stirred up by the pressure cleaner? I'd see your doc and maybe ask for an x-ray to be sure...

yep I second getting it checked out. I have carpel tunnel and its a blinking nuisance. I wear a splint every night to bed but nights when I don't I wake with numb fingers.

Hope it gets better soon x x x
