I am a 67 year old female who has been in good health. I was put on 40 ml of Zocor about three years ago. After taking it for six months I asked to be changed to Lipitor because of stomach pain I felt was caused by Zocor. I didn't have stomach pain with Lipitor. A year ago I must have had a senior moment because I changed back to Zocor. Generic Zocor was much less expensive than Lipitor. During the past year I developed most of the side effects that everyone is mentioning: stomach pain, nausea, memory loss, sleep problems. I didn't relate this to Zocor. Then I woke up one morning and could not stand without severe pain in my left knee. It hurt to touch it. A week later my right knee developed the same symptoms. This didn't happen gradually. It was very fast. I can also identify with those who say that back pain makes them walk bent over. The pain also radiated into my shins and one heel. I wept when I found this site and read all the posts about similar symptoms. I decided to go off the Zocor for a month and see what happens. I've been off it for three weeks today. The pain is MUCH less but not gone. I'm hoping that it will continue to get better.
