I started on 40 mg of lipitor when I was 43 and my new doctor listed to the history of heart disease in my mother and older sister. My mother had a heart attack at 62 and again at 64 and had a quadruple bypass heart operation. My doctor knew that Lipitor was a drug to lower cholesterol and he asked me to try 40 mg to see if I could avoid having heart disease. I have no heart diseased that I am aware and I will be 83 in August 2023. I thought I noticed pain from Lipitor when I was in my late 60's and I stopped for a month, but decided Lipitor was not my situation. I further asked my doctor, and he replied that "we all" as we age experience different feelings as we get older. Why he says, all the time "growing old ain't for sissies". The human body as it grows older your mind could be the culprit!
