My cardiologist prescribed 40mg zocor in Dec 07, I couldn't understand why I was feeling tired, having muscle aches and pains and just recently every joint in my body was hurting and inflamed. I haven't been able to do anything but lay around.. even getting up to take a shower or use the restroom was a task for me. I was also very depressed and just not myself. I am 47 and I have always been very active and full of energy and couldn't understand what was happening to me. I never would have thought that this horrible medicine was the culprit. I quit taking it on Sept 15th and already feel so much better. I can only hope and pray that there is no long lasting effects. I can manage my cholesterol without it!!!!!
