Have been taking Lipitor for about 11 years. Fairly recently increased dosage from 10mg to 20mg. For about the past week have begun to experience tingling, numbness and general ache in legs, arms, sometimes cheeks and fingers. Spoke to doctor who seems stumped by these symptoms. Will be doing blood tests to test thyroid, anemia, B-12 levels etc.etc.etc. Given what I have read here I can't help but think I know what the problem is. I should mention I had quadruple bypass 12 years ago so the doctor doesn't want any spike in cholesterol levels.
