I have pain in my right upper arm and shoulder, it is much worse when I lay down, I can barely move my arm,? I have a prescription from a doctor for motrin, but it doesn't seem to help any, the pain seems to be in the muscle and travels up and down the upper arm, and is sometimes sharp enough to make me want to cry.  any help, ideas, suggestions are appreciated.

Summarized question: How can i get rid of a sharp pain in my right upper arm and shoulder?
