Based on the available information, I do not have personal experiences and cannot directly answer if I have experienced lip stiffness with Lipitor use. However, I can provide you with information regarding Lipitor and its side effects.

Lipitor is a brand name for the drug atorvastatin, which is a statin, a class of drugs often prescribed to lower cholesterol levels [1]. According to the Mayo Clinic, common side effects of atorvastatin include cold-like symptoms, such as a runny or stuffy nose, sneezing, or sore throat [2].

Regarding lip stiffness, the Mayo Clinic does not list it as a common side effect of atorvastatin [2]. However, a study published in the Journal of Clinical Lipidology reported a case of transient lip and facial edema associated with atorvastatin use [3]. While this study does not specifically mention lip stiffness, it is worth noting that there have been cases of lip-related side effects associated with atorvastatin use.

In summary, while lip stiffness is not a commonly reported side effect of Lipitor (atorvastatin), there have been isolated cases of lip-related side effects associated with its use. If you are experiencing lip stiffness or any other unusual symptoms while taking Lipitor, it is essential to consult your healthcare provider for further evaluation and guidance.
