http://www.medications.com/effect/view/40815 Apr 2009 I am a male 58 yrs old recently had a leg & knee operation, experiencing very bad lower back pain along with cramps on affected leg which is on a cast. I started taking Lipitor about a year ago. Tue, 21 Apr 2009 11:17:14 -0400 http://www.medications.com/effect/view/40815?item=19060 I suggest that you stop taking this dangerous drug. Lipitor can cause MANY side effects. Drs. and the drug co's have a HUGE racket for the anti-cholesterol drugs . . .big $ and while people suffer. Your body/mind needs cholesterol to function.
