I saw my primary care about 4 weeks ago because I had a sore shoulder and my arm was weak. It had been bothering me for about 6 weeks. He suggested I discontinue Lipitor and prescribed naprosin. It has not helped. Other joints are also sore. Today my left hand, at the bottom of my thumb is very sore. With my right shoulder weak and painful, I relied more on my left hand to open doors, lift and carry stuff, etc. Today I feel it will be difficult to do what I need to do. I m 66, still working, and have been fairly active.
