Based on the information provided, I was unable to find specific data on the frequency of flexibility issues reported by Lipitor users. However, Lipitor (atorvastatin) is a statin medication used to treat high cholesterol and prevent cardiovascular disease [1]. Common side effects of Lipitor include headache, muscle and joint pain, and digestive issues [1].

Musculoskeletal symptoms, such as muscle and joint pain, are more commonly reported with statin use, but flexibility issues are not specifically mentioned in the literature as a common side effect of Lipitor [2]. It is important for individuals taking Lipitor or any medication to report any new or worsening symptoms to their healthcare provider.

In summary, while flexibility issues are not commonly reported as a side effect of Lipitor, individuals taking the medication should monitor for and report any new or worsening symptoms to their healthcare provider.
