I am a 69 year old with elevated cholesterol (280). I have been on 20 mg Zocor for 27days. It seems to have effected my sleeping pattern, some headaches, throat irritation, and most recently soreness in my calves and feet area. Normally I could be on my feet for hours at a time with no problem, but not now. I have several friends who are on Lipitor with no reported problems. I felt great before starting Zocor, so plan to talk to my Dr. about either stopping or switching.
