Lok symptoms and conditions

I have been taking LIPITOR for about 1.5 years and have been feeling the cotton head but thought it was allergies. for about 8 months or so I have been feeling pain on the left side of my chest and upper back by the shoulder plates. I've told my doctor and had several tests done incl. MRI, C-scan, etc. Once I even had to go to the emergency room thinking I was having a heart attack. But the doc. said the EKG was normal and that it might be muscular. I have not read that anyone else is having the chest symptoms. This is very scary to me. Lately I feel my neck getting stiff and I am also constantly tired and keep waking up at night and have a hard time going back to sleep. I don't seem to have the arm or leg pains that most people here seem to be suffering from but am now convinced it's LIPITOR since it is the only prescription medicine I am taking. I would appreciate hearing from someone who has had the same symptoms I've described above. I stopped taking Lipitor about 4 days ago and do feel already less tired but the upper body pain is still present.
