I have been on lipitor for five weeks and I've been trying to figure out during this time why I feel achey,sore mucles,stiffness in my joints(feet and hands especially)back ache, just a general overall achey condition. I've had every blood test run to see if I have any signs of arthritis and I don't. People including doctors have told me I probably have Fibromyalgia, so I've been looking for how to treat that, then I read all the side effects of liptor. I am stopping the lipitor today and hope this pain will all go away. I've been extremely healthy all my life (57)until this. STOP TAKING
