I was playing a game last night and the circulation to my left arm got cut off by the desk. i didnt think anything about it because usually the blood just runs back through and your fine again. Well it didnt work out like that and about 18 hours later i still have a numbing sensation in my left arm more towards the elbow all the down to my hand. It just felt like the blood didnt get moving again like it ususally does. Any suggestions on what might of happened or how to fix this problem?
