high cholesterol
"Was on 10 mg of Atorvastatin, my cholesterol went way down.  After about 6 months, I developed severe cramping in back of legs, especially behind my knee cap.  Pain came every night and every morning.  There were times I couldn't pick my legs up to get over the curb.  Sometimes I wasn't sure I was going to make it to work.  Pain was in both legs ran down from behind my butt checks to my heel."
