Lipitor and liabilities

I was on Lipitor for either two or three years, maybe more, can't remember, it was around 2003. About a year after starting the meds I started losing my balance, like my feet were heavy and wanting to not lift themselves up when stepping off a curb. I was in fear of falling. After being a professional dancer for many years and still having excellent muscle tone I was shocked by this muscle problem. Then I developed shooting pains in my thighs, and eventually I had an incident where my one leg just gave out and I couldn't walk. It was something in the hip/leg joint. Went to an orthopedic doctor, got x rays and m.r.i., he found nothing. I stopped taking Lipitor because I had spoken with other friends who were having leg pains. My regular doctor would not admit to anything wrong, just kept telling me I needed to stay on the drug, which infuriated me. He also kept blaming the muscle weakness and pain on my weight; which I have never had a problem with before.
The shooting pains in my thighs was all the time, including at night and woke me up at night. This was unreal. Even after walking miles I had these shooting pains, so it wasn't an exercise issue at all, but it certainly did deter me from exercising more often.
Now the pain and swelling is mainly in my knees. I can hardly walk, feel like I am crippled, and have lost my job over not being able to walk around and show apartments! I can't walk steps anymore at all, I am only 55 years old! No matter what I do, the pain and muscle weakness is progressing, I've seen a Chiropractor, a nutritionist, and now I'm going to see a Rheumatologist. I believe I have permanent muscle damage from this drug, no one can tell me otherwise.
Also, I have experienced the gradual increase of brain fog over the last two years. I am scared to death this damage is irreversible.
