This is a great Thread. I too have this problem. But it stemmed from an accident 20 years ago. I was riding a motrocycle about 20 miles an hour and this lady comes out from between two cars. I brace and lock my arms straight holding the handle bars as her legs hit my engine and then her body side swipes my right shoulder. I didn't fall but she spent a week in the hospital
. That same day I started to feel a tired shoulder when I washed my hair. Never got it checked out. But years later went to a chiropractor. He said that the pain in my neck through my shoulder and into my bicep stemmed from the shoulder blade. Sometime my shoulder feels fine but at times I can't bench press or do chest flys. Cab someone help???....thanks r
