Male age 50. Used Lipitor 20mg for 10 months, having previuosly taken Lescol and Zetia. I am suffering very serious side effects including: slurred speach, loss of muscle mass and strength in right arm and hand, sore right foot, muscle tremors, severe cramps in legs and abdomen. I stopped Liptor 6 weeks ago. Cramps have stopped but little improvement in other conditions.
