Hello. I Have Been On Lipitor For About Four Years

Hello. I have been on Lipitor for about four years now and I noticed that recently I have hip pain in the morning on the left hip only. I take 10 milligrams of Lipitor every night before bed. Do you think it is causing this left hip pain? It does not last all the time but it's periodic. during the day, it does not hurt at all. thank you. Tom.
