I fell the other night skating. I fell on my bottom, but when I hit I felt a sharp pain about an inch from my spine near my right shoulder blade. It was hurt so bad I did not want to move. It hurts to move too much, I can not take deep breaths or yawn. Also when I sneeze I inhale to a point and it hurts so bad it takes my breath. I thought it was the muscle at first so I tried to massage it, but it started hurting around my side and into my front. I am wondering if it is a cracked rib, and if so what to do about it. If not what could it be?
