Replacement therapy symptoms and conditions

I took Lipitor for about 6 months. Right after I began taking it, my legs, especially my right leg began hurting. I got off the drug at 6 months because my legs hurt so badly I could not sleep at night. I just had X-rays of my right knee done, and I have almost no cartridge left on my right knee cap. I now may have to have knee replacement therapy. My doctor that put me on the lipitor said that it was not the lipitor that caused. I think it is very odd the pain began when I started the drug.

I've been on 10 mg of Lipitor for approx 2yrs. A few months back I began experiencing severe constant right hip pain. A could walk through it, but had many sleepless nights due to the unrelenting deep pain. I had difficulty lifting my right leg without support from my arms. I'm 54 and otherwise in pretty good health. I stopped taking the Lipitor about 2 weeks ago and while I still have some pain it has decreased about 75%. I can sleep at night and am even pain free some of the time. If anyone has had a similar experience would appreciate knowing and if the pain eventually subsides and any suggestions to support the healing process.
