Hi, I have gone through your medical history carefully and understood your concerns. Lipitor is a statin medication used to lower high cholesterol levels. Its mechanism of action involves the inhibition of the enzyme HMG-CoA reductase, which is particularly present in the liver. Unfortunately, this enzyme is present in all muscles of the body. This explains why you are having horrible pain all over your body. OxyContin won t help much as long as you do not eliminate the primary cause: Lipitor. Discuss with your doctor about another alternative to Lipitor and report this horrible pain as its side effect. Once you stop Lipitor, it will take a few days until you won t feel the pain anymore. I also recommend to follow a healthy diet and lifestyle regimen to keep your cholesterol numbers within normal range. Hope this helps. Dr.Albana
