I was reading the various side effects and I have one more to add...

I have been taking 80 Mg. of Zocor which I was switched from lipitor about 8 months ago and he just upped my dose of zocor from 40 to 80 mg...I know what you mean about the vertigo..I have been getting that alot lately and it is very scary! my legs hurt all the time , mostly in my knees , I have a hard time walking up the stairs..I am 43 years old and shouldn't feel this way..I started reading some of these side effects and came across yours with the vertigo... I just really haven't felt the same at all since I have been on this medication...

Yes...I have had sensations of the room spinning several times. Once, it lasted all day. Have been on Zocor 20 mg for more than a year. My doctor just called to tell me to stop taking Zocor IMMEDIATELY because by lab work just showed that my muscle enzymes are HIGH. I have been having muscle aches in legs, knees and hip for several months. Hope it goes away now.
