After being on Lipitor for over 3 years, I decided to stop taking it in OCT 07 and start seriously working out to try to control my cholesterol. I started feeling much better within a month. I was not near as stiff and my plantar fasciitis was much better. I attributed this to loosing about 12 pounds and the physical exercise. At my physical in JAN 08, my doctor said I should get back on Lipitor. Within a few days of starting to take Lipitor again I was very stiff and sore and my plantar fasciitis was getting worse. If I sat for a while it was very painful to get up and start walking. I stopped taking Lipitor again and saw an improvement in my stiffness and soreness.
