Unfortunately, the sources provided do not contain information on specific stretches that are best for Lipitor users. Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. The sources provided discuss the patent status of Lipitor, the potential side effects of statins (a class of drugs that includes Lipitor), and the possible causes of muscle pain in statin users. However, none of these sources provide information on stretches or exercises that are specifically recommended for individuals taking Lipitor or other statins.

It is important for individuals taking Lipitor to speak with their healthcare provider about any concerns they have regarding their medication and to follow their provider's recommendations for managing their cholesterol levels. If an individual experiences muscle pain or weakness while taking Lipitor, they should contact their healthcare provider for further evaluation and management.
