At one point when I was in my thirties, both my arms began to hurt when I lifted them; this lasted maybe a couple of months, but the pain went away all of the sudden. Now I m 48 and the pain is back, but this time it doesn t go away. It started again, mainly in my right shoulder; I have to accommodate my arm in certain way before I could move it, I cannot make any sudden moves with it. But, now the pain is traveling down my arm up to my elbow , in both arms, but mostly my right one. What could it be?
