Zocor and charley horses

Just started taking zocor 3 weeks ago. I have noticed some of the symptoms listed by others. I am having trouble with constipation. Now my hemorrhoids are flaring up. My whole bottom is hurting. I also am having charley horses in my legs. I haven't had this problem for years. Has anyone noticed these problems?

This is the second time my Doctor has put me on Zocor. Since taking this medication, both times I have experienced pains in my hips and down the sides and backs of my legs. It doesn't bother me as much on soft, carpeted surfaces, but becomes very uncomfortable on hard surfaces. I also have a good deal of pain in my legs if I try to pick up a heavy item to move it. I am 67 and have always been strong, but this has caused me to feel like a really old lady. Has anyone else been successful changing to another medicine that does the same thing? I feel as if my muscles are tied up in knots, and I guess they are since I also experience more charley horses.
