Started Lipitor 5 months ago. Noticed a tingle and slight pain from left elbow down to hand. Had to go off of Lipitor after two months b/c of upcoming right knee replacement. Started taking Lipitor 6 weeks ago after surgery. I have started having severe shoulder pain and upper pain in the left arm and again the tingling in elbow and hand. But the worst is I now have a pain and weakness in my left knee so severe that when I first stand it takes a few minutes before I can put my weight on that leg. Have to use a cane for first few steps and then pain subsides and strength comes back and I am able to walk. Went to Dr yesterday and he did not think Lipitor was the cause, but agreed I should go off for a month. Anxious to see if anything changes or was this all a coincidence.
