Hello there,

I have been meaning to answer this post for quite some time... I was just wondering if, since you describe the feeling in your arm not so much pain, but wanting to hit it, and it is driving you nuts... if you could possibly have restless leg syndrome? My mom had RLS, and she had it in both legs and one of her arms. She described it as driving her up the wall and wanting to hit it, etc... just like you.

Just a thought... as I know it can affect your arms.
