I am 70 and a reasonably fit and active woman who still works part time. I have been taking Crestor 40mg daily along with a blood thinner (plavix) and blood pressure tablet (ramipril 5mg) since having a cardiac stent 8 years ago because of a single blockage in my left main artery. In the last 12 months I have experienced pain in my legs particularly when sitting for long periods driving. Recently I ve been getting muscle cramps in my lower legs during the night, occasionally severe. Could these be the result of the statin and should I take the co-enzyme q I ve just been told about?
