numbness in right arm

For the past month. I have had numbness start at the top of my arm. And goes down my arm and forearm, and down to my thumb and frist finger. It comes and goes though the day off and on.  When i sit at my desk it comes and feels like my blood is cut off and somebody is sticking pin in my wrist, thumb, and finger.

Any Answer on what this is??????

do you mean your arm goes dead so you cant move it? if so see you doctor asap! with anxiety you can get numbness where you cant seem to move your fingers and your arm seems numb but can move it. you may be sitting awkwardly at your desk n have a trapped nerve
