Lipitor and fosomax

I have been taking Lipitor !0 mg since Aug. of 06.Recently I have experienced progressively increased back,& hip pain & stiffness. Sometimes when I get up from chair or bed it is becomung harder . I thought that It was osteoarthiritis but my recent bone scan was unchanged from 3 yrs ago. (I recently stopped the Fosomax due to Gerd) I had hip & hips xrayed last week and will get results soon. In the meantime it occured to me that the problem may be S/E'S from the Lipitor.even I take COQ_10 a few X's a week. Have been off the drug for4 days now and the severe pain is subsiding anf I actually went for a short walk today as test. What do you think? Iam a retired RN and knew to watch for muscle problems but have had back pain (not severe)for years so I thought it was joint problema when hips started to occur. I am done with Statins.
