I just found this site and I'm totally AMAZED at all the similar complaints I have. I am a 46 year old female and have been on Zocor for about 6 years. My cholesterol is high, due to heredity. I've gone from 20mg, to 40 mg, to 80 mgs. I had leg cramps so badly with the 80 mg. that I just quit taking it. I was put back on 40 mgs. and still have many of the complaints.. i.e.... chronic muscle pain in neck, shoulders, arms, legs... chest pain/burning just doing minimal walking (saw cardiologist and had treadmill - nothing found)... a rash that comes and goes on my face, especially on and around my eyelids... insomnia... strange to horrible dreams... sudden lower abdonimal protrusion (never had that in my life!)... inability to lose weight... So, there you have it. I will be consulting with my doctor and getting off this horrible medicine! Diet and exercise will be a forever friend to me. I'm so glad I found this site.
