Osteoarthiritis symptoms and conditions

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.

Great reduction in cholesterol levels! But suddenly I felt absolutely without any energy to perform daily tasks, and, simultaneously both knees were swelling and it was difficult walking. I immediately stopped taking Zocor and went to my heart doctor. He agreed that I had done the right thing. I had also been taking Vioxx for lower back pain for a while. Don't know if there was any interaction.
My heart doctor sent me to a rhumatologist. He said there were no real problems with the knees except some expected osteoarthiritis, indicating a slightly greater wear in the cartledge on the inside of the knee joint versus the outside. He took some fluid from one knee and only recommend I get some physical therapy. I waited about four months before following up on the therapy. The physical therapist told me immediately that my problem was only mechanics...the way I walk and that if I would practice walking properly then I would be OK. I suspect there is some truth to this but the real cause of altered walking in my opinion was the pain from taking Zocor.
Please let me know if you have found solutions to this. I am 58 and otherwise quite healthy.
