Based on the information provided, there is no direct mention of muscle pain as a result of combining Lipitor and Tums. Lipitor, also known as atorvastatin, is a medication used to treat high cholesterol [1]. Tums, on the other hand, is an antacid used to relieve heartburn and indigestion [3].

According to the Mayo Clinic, potential side effects of Lipitor include muscle pain, but this is typically associated with the use of Lipitor alone and not in conjunction with Tums [2]. The GoodRx website also does not list muscle pain as a potential interaction between Lipitor and Tums [3].

However, it is always important to consult with a healthcare provider or pharmacist before combining any medications or supplements, as individual reactions can vary. It is also important to follow the recommended dosages and instructions for each medication.

In summary, while muscle pain is a potential side effect of Lipitor, there is no direct evidence or mention of muscle pain as a result of combining Lipitor and Tums.
