http://www.medications.com/effect/view/22281 I am 53 years old and have been on 10 mg of Lipitor for at least 5 years. For the past 3 years I have been experiencing tight muscles in my back and muscle spasms on my right side. I have had the following tests done - all of which came back negative: CT Mon, 16 Jul 2007 07:19:59 -0400 http://www.medications.com/effect/view/22281?item=748 I also had a similar experience with Lipitor, then Crestor just made me feel overall ill with muscle weekness, then Vytorin gave me a horrible sinus infection which turned in severe bronchitis. I have allerted Lipitor ( Pfizer) and the Vytorin company.

Available at super markets, health food stores etc... but cheapest on-line. I was told 300mg a day but had to go up to 900 mg a day and the symptoms started to lesson in 3 days and were GONE http://www.medications.com/effect/view/22281?item=1560
