Zocor and politicians

I am a 58-year-old woman that changed from zetia to zocor about 6 months ago because of the price of zetia AND I had tolerated the zetia ok but my chol was still elevated. My initial dose of zocor was just 10 mg, even though I had a lot of aches and pains from the slighest exertion I really did not connect this to zocor. After my last checkup, the doctor wanted to up my dose to 20 mg daily because my chol was 228 (liver functions were all ok). I have been doing that for 6 days and my legs have become very achy, my left knee has swollen above my kneecap (which is very painful), and my lower back hurts. I have been having a lot of trouble sleeping and feel draggy all the time. I got on the net to research these symptoms when I found this site. I am going to go off this med and see if my condition improves! I will post an update as to the results.
