I Have Been On Zocor For 20 Years And Have

I have been on Zocor for 20 years and have always had sore joins and aches in my body but in the last 12 months these pains have become very servere and I find that I am taking pain relief most days. I have a very bad family history of heart disease and at 44 years had a triple bypast after three heart attacks. I am also an insulin dependant diabetic. Could zocor be contributing to these ongoing pains.
