About a month and a half ago i had a huge bike wreck. I got knocked out and i lost so much blood i couldnt move. I had a huge gash in my hand, my knee, my hip, and my arm. I got about 38 stiches in all.
Anyways everything has healed but my arm. My skin turned black before it healed and it came off. But now all the sudden its hurting again and there is this brown spot thats numb and its growing bigger. I have no clue whats wrong with my arm. The brown part is really numb too and its not on the place i got the stiches at either. The scar and where i got the stiches are in a V shape just above my elbow. And the brown numb part is in the middle of it all. Please Please help me. Its really scaring me.

Thanks
Amber
