Fit as a fiddle symptoms and conditions

I took Lipitor for about 2 years- 5 mg.
Leg cramps-soreness throughout my muscles- very sore buttocks-
my legs are shaky- if I use them too much; (as in walking 3 miles)
I am (was ) an avid body builder that could squat with 100 lbs- and now ( I am a health conscious -non drinking- NO other medication 104 lb slim female) have quivering legs if I stand for too long. I even had a muscle biopsy- and it cam back negative- I have not had a statin for 6 months- but I still have cramps- and abnormal liver values- and I have NO other conditions-I have been scanned from head to toe - open MRI- closed MRI -but the muscle stiffness- soreness- especially legs- continues-
does anyone know how long it lasts? I have also been tested for liver cancer- thank God-negative.
I really feel that Lipitor did this- has anyone else gone from fit as a fiddle to a quivering -achy person- I have gone through 5 doctors- internal - gastrointestinal - neurologist- hematologist and all is negative- just high liver values and muscle pain. Thank you so much.Maxine
