Arthrtis symptoms and conditions

I am a 52 year old male.8 years ago I had a heart attack.2 stents were put in.I have been on lipitor for the past 8 years.I was on 80 mg. for years,cholesterol got so low the Doctor reduced it to 40 mg.I lived with minor soreness,thinking it was age,arthritis,and a side effect of my very physical job.3 weeks ago joint pain started getting worse! Knee, hips,and especially the shoulders.It got to the point I could hardly crawl out of bed.Feb.20 called the doctor and he told me to stop the lipitor immediately! Today Feb. 24 pain is way less already.I wonder now about long term damage to muscles and joints! I am supposed to call him at the end of the week,very curious about what the conversation will be like. I do not plan to go back on the lipitor especially after reading this web-site.Thanks
