Inflammed Bursa in the Shoulder?

I have that problem. Though i can throw my shoulder out lifting something as easy as a gallon of water. I suggest you see an orthopaedic doctor about your shoulder. Surgery is an option for mine, but I am not ready to be down for that long. I have learned to do everything left handed anyway. Sometimes that clicking may be caused by a bone spur. My sugg: see a specialist, or get a second opnion. You don't have to live in pain
