I have been on Lipitor for about 3 years. I have constant pain in my upper, outer arm area. Also when I rub this area I feel lumps. I'm having knee problems which I know is somewhat related to arthritis but the pain changes. Some days when I get up from sitting any length of time I have to wait until the bend of my legs relaxes or whatever it does before I can walk. Thinking this might be the hamstring area. Still taking this drug but am seriously considering stopping. So glad I found this site and have emailed it to my friends who are also on this drug.
