Hello all, after reading all of your messages I am convinced now that the Lipitor is to blame on my symptoms as well. I began 10mg of Lipitor about 3 years ago and this past February was increased to 20mg, my cholestral readings was at 98 and now at 90. I also quit smoking in February. In April started to experience extreme pains in my arms and back, thought it was the mattress or pillows have replaced every pillow in the house, and have begun pricing mattresses. Have extreme bloating, gas and constipation. Went to the Drs. and was told its a reaction to quitting smoking as nicotine is a natural laxative. Sounds beleivable, never though of the Lipitor increase. Breast extremely tender and sore, went to the OB, had a mamograpghy everything fine, OB suggested researching Lipitor and bingo I'm a believer. Called cardiologist today and she has immeditaly lowered it to 10mg, and wants to see me in 3 weeks as a follow and possible wean off all together. I need to research the cholestral numbers and see how good or bad mine are at the moment. Again thanks everyone for taking the time and writing about your experiences and reading everyone elses. Good luck to all
