Lipitor is a medication used to lower cholesterol levels in the blood, but it can also cause muscle pain and weakness as a side effect [1]. According to a Harvard Health Publishing article, some people may experience muscle pain and weakness when taking statins like Lipitor, and the pain can be severe enough to interfere with daily activities [2]. The article suggests that regular stretching and exercise may help to alleviate the muscle pain and weakness caused by statins [2].

A study published in the Journal of Clinical Lipidology supports the idea that exercise and stretching can help to counteract the effects of statins on muscle pain and weakness [3]. The study found that participants who engaged in regular exercise and stretching had less muscle pain and weakness than those who did not exercise [3].

In conclusion, while Lipitor can cause muscle pain and weakness as a side effect, regular exercise and stretching may help to alleviate these symptoms [1][2][3]. However, it is important to consult with a healthcare provider before starting any new exercise program or making changes to your medication regimen.
