I am currently 44. I have been on Lipitor since December 2005. I was going through breast cancer at the time. I have a family hx of heart disease and high cholesterol. I have been experience many annoying joint aches, muscle pains, and so many other others described. I had to have a bone scan done to make sure I didn't have bone cancer. I am now convinced that after reading all your entries (and my in-laws telling me of these things), that Lipitor has been my problem. My family Dr. had me stop it for 3 weeks and then go back to see what difference it made. Some muscle pain subsided. Came back when I started it again. I am now going to stop taking this and see what other alternatives I have. Your stories have been incredible and helpful. I'm sorry so many have had to endure so many problems but am grateful you have shared your experience. God Bless you all.
