I fell at work almost three months ago and hit my right upper arm towards the back, near my armpit ( on a trash can.. Lol ) I had an immediate shock and couldn't feel my arm for about 2 minutes. It still hurts, the immediate coloring was a dark purple. It hasn't started to fade at all- now it's a dark brown and still hurts. Same size. I don't have any blood disorders that I know of. Please help!
