Curtailed symptoms and conditions

I was prescribed Lipitor last Oct (2005), and in a short time was experiencing such leg pain and mental "fog" that I was in the doctor's office complaining about it every month. I was at first attributing it to stress at work and home, but when my normal daily exercise routine was so severely curtailed because of the pain, I had to start looking at other things. I had once been able to ride my bike and do aerobics, kick-boxing, and other more strenuous activities without tiring or having such muscle pain that I was unable to move, but now pain and fatigue are just parts of my life --- and I'm only 47! My doctor took me off the LIpitor when I finally complained LOUDLY about my leg pain, but was told it might be months before it was completely out of my system. I've since become worried that the damage this prescription has done might be permanent! I so want to get back to my old self! Does anyone know if this is something that will never go away?
