I would like to worn anybody who is about to start to use Lipitor to please read the side effects first. I have been using Lipitor 40 mg for the past four years, and durning that time landed 3 times in hospital (taken by ambulace) with misterious chest pains, plus several visit do the doctor with the same complain. After the check-up , they told me I had muscle inflammation and was given strong pain-killers. The pain in my chest muscles was so severe, that I couldn't move, or take a breath... I also experienced progressing lack of concentration, hair-loss, numbness in my both feet, memory loss, and bad itching on my legs. Just recently I had a severe pain in my chest again and started to ask myself what is causing it. I read the information leaflet (for the first time...!!!) from my Lipitor tablet box and decided to stop taking it. It's been mow 4 days, and no pain. However, I still wonder if there is some permament damage done to my system, as it is too early to tell.
