I took Lipitor for 36 days. At first I noticed only some increased heartburn and constipation. Then came the insomnia, restless leg syndrome, and increasingly severe depression. One day I took my usual walk with my dog and felt as though I were walking through waist-deep mud. I went home and took a nap and when I awoke I felt as though I had been beaten with baseball bats. Every muscle in my body ached. By the next day, I was suffering with nausea, upper abdominal pain, and could barely stumble to the Dr.'s office. She drew blood to test for muscle damage and it was negative, but told me to stop the Lipitor. Many of the symptoms subsided almost immediately. Still, 3 weeks after stopping the Lipitor, I have constant muscle pain, especially in my legs, also weakness and fatigue that prevents me from living my normal life. I also have a constant tingling and burning sensation in my feet, and muscle twitching. I wish I had researched Lipitor on the Net before taking. I am very angry that this drug and others like it are being pushed on the general public by the medical community and the pharmaceutical companies. It is sad to read the experiences on this forum. I wish you all the strength to recover and regain your lives.
