I have been on zocor for 7 weeks and almost immediately upon taking have experienced leg cramping. When I saw dr. about 4 weeks after starting zocor I told him that 2 hrs. after taking med's I have muscle cramping. He disregarded my concern. Since then, I have experienced more severe pains in my legs, shoulder tightness , back of neck spasms. This morning spasm were severe in neck, feet, calfs plus blurred vision. I am in route to the dr. to tell him that I am discontinuing this medication.
