I am a 44 yr old male and I have been on Lipitor for several years. I started getting muscle weakness but thought nothing of it other than getting older. I am starting to feel fatigue, pain across lower back and buttocks legs and arms. I have also started to notice memory loss both short term and long term which has effected me alot lately. I am going to stop my Lipitor after reading all these articles with similiar side effects. I will report my progress when I see a difference. I can only hope that the memory loss goes away so that it doesn't effect my work or ability to work.
