I have now been off Lipitor for 3 weeks and am feeling less fatigue and my hips and thighs are not hurting as much. Still pain when walking up stairs. I ask my General Practioner for a CPK test (muscle test). My Cardiologist did not agree with me that Lipitor was causing my hip and thigh pain and weakness. Sure enough the test came back slightly elevated. Because of a heart attack, my doctor wanted me on a statin drug. I tried 2 with the same results. My liver test always came back good so that is all He cared about. Now I have some muscle wasting. I'm not sure if that can be corrected but whatever I will never take Lipitor again.
