Lipitor and high energy

I have taken lipator for a number of years,within the last 3 months I have had more pain in my left shoulder and arm than any pain I have ever had in my life,I was told I was told I had extensive degenertive disc desease in my neck and spine, I had a bone density test about 2 yrs ago and there was no sing of it.I was also given sinthroid abouth 4 months ago for my aches and pain in my joints and for fatigue,when I ask if the sinthorid could be iteracting with the lipator ,the doctor said it was possible,but didn't take me off of either one,I now have a frozen shoulder and am taking phyical therapy,I just at this moment thinK I will take myself off of both of these medications,Ihave a pretty big problem with my memory,I have gone from being a high energy,fun loving person to trying to figure out what to take or do for the pain.I sometimes feel like I am lost if I drive after dark.
