I broke my arm, my radius, near my wrist two weeks ago. I wore a cast for ten days, but now I'm wearing a splint. For the several days, I have had an increasing amount of mild discomfort that feels like my blood circulation is being partially cut off even when I loosen the splint completely. The doctor told me to go to the hospital if I felt tingling or numbness, but I don't know if this is tingling or not. The fingernails on my broken arm side aren't quite as pink as those on my other hand, but they look reasonably pink. I tend to have low blood pressure. I'd appreciate hearing what you think.
