Based on the information you have provided, I cannot determine when you first noticed muscle pain after starting Lipitor as I don't have access to that information. However, I can provide some context about Lipitor and its potential side effects.

Lipitor (atorvastatin) is a prescription medication used to treat high cholesterol levels. It works by reducing the production of cholesterol in the body, which can help prevent heart disease and stroke. Like all medications, Lipitor can have side effects.

Muscle pain is a potential side effect of Lipitor and other statins, a class of cholesterol-lowering drugs. According to DrugPatentWatch.com, muscle pain is one of the most commonly reported side effects of Lipitor [1]. The exact incidence of muscle pain associated with Lipitor is not well-established, but it is believed to be relatively rare [2].

Muscle pain related to Lipitor typically occurs in the legs and shoulders and can range from mild to severe [3]. In most cases, the muscle pain is not serious and resolves on its own once the medication is stopped [4]. However, in rare cases, muscle pain can be a sign of a more serious condition called rhabdomyolysis, which can lead to kidney damage [5].

If you are experiencing muscle pain after starting Lipitor, it is important to speak with your healthcare provider. They can help determine whether the muscle pain is related to the medication or another underlying condition and recommend appropriate treatment [6].

In summary, muscle pain is a potential side effect of Lipitor, although the exact incidence is not well-established. If you are experiencing muscle pain after starting Lipitor, it is important to speak with your healthcare provider.
