I am a 51 year old male who has taken a 10 mg dose of Lipitor for years. I thought it was a miracle drug as I had no side effects. I am a retired police officer and Army Reserve Officer and have maintained good physical shape. I retired a year ago. About the same time, my doctor raised my dosage to 20 mg. During the last year, I have had physical problems pop up. They include not being able to make it through the night without having to get up and go pee. I realized that it is because of reduced flow and I do not fully purge when I do go. I went to my doctor and had my prostrate checked; it's OK. He said it was just getting old. I thought I have been getting arthritis. When ever I sit for very long, I get joint/muscle pain, I have been having pain in my hands and feet and need to stretch when first getting up in the morning. The worst is my knee. It was surgically repaired 9 years ago. The last year it started hurting bad enough that I must sleep with a pillow between my knees and still wake up from pain at night. Eight months ago I moved. My mail order prescription (90 day supply) was recently running out of the 20mg Lipitor, but I found an old bottle of the 10mg dose and started taking it until I identified a new doctor and got a new prescription. My symptoms began to disipate That lead me to start thinking about whether lipitor had any side effects. I never thought of it until this morning. I googled Lipitor side effects and found this site and started reading about people with similar issues. I had no significant problems with the 10mg dose and may just reduce again to that level. I'm making an appointment today with my new doctor to talk about it.
