Don't know if it is the same thing but quite often when I have been on the computer for a while [not literally

] I get pins and needles in one arm and hand. Are you right handed by any chance?. I am but where I use my right hand for the mouse my left arm must just rest in an awkward position on the desk, perhaps on a nerve

, although I don't feel it at the time
It often takes a few days to go but returns just as quick.
I would still get it checked out by a doctor before having any other kind of treatment.
