Ouch...

Recently in a game of basketball I accidentally fell over onto my shoulder while trying to retrieve a ball. At first I dismissed it since it felt like a light sore on my shoulder but a few hours later, it came back with a vengeance. Every time I try to move my shoulder, a sharp pain would emanate from my shoulder which restricts the movements of my right arm. The pain itself is a totally different story and no words can describe the excruciating pain whenever I attempt to move my arm or shoulder. Hopefully it's not a serious injury because I've read horror stories from medical journals on what happens when someone falls onto an outstretched hand or on their shoulders...
