Zocor and cysts

I have suffered from Fibromyalgia for over 12 years so muscle pain, fatigue and memory loss is a way of life. It concerns me that some of the increased pain and fatigue could be related to Zocor. I have been on it approx on year. The new thing I am experiencing is knots, cysts, tumors what ever they are are showing up all over my body. I have one in the muscle of my left shoulder and have experienced extreme pain with limited use. Has anyone else experience this happening to them? Taking Zocor is the only thing that I have done differently in the last year. Going to the Doctor about all of this in 3 days. Thanks Debbie
