diagnosed several montha ago with a jammed ac joint and rotator cuff and bicep tendinitis. The shoulder was injected and tried therapy for several weeks.There was some slight improvement. The effect of the cortisone and therapy wore off about the 6 week. Now I have a worse problem than before the pain radiates into the elbow joint. The bicep area will ache to the point of cramping in the middle of the night. any suggestions?
