CPK Levels

I am a 54 year old male who has been very active all my life. I try to work out 3-4 times a week doing both weights and cardio. I had been taking Lipitor for about three years and started noticing severe muscle soreness about 15 months ago.

Blood tests came back with elevated CPK levels. I went off Lipitor last January and immediately felt better however in Jun (6 months later) my CPK will still above normal 192. The doctor ran another test the showed the CPK MM level to be at 192 and he put me back on Lipitor ....I started having serious muscle soreness and went off the Lipitor again and met with a neuerologist  who has run a number of tests that have all come back negative including an Ischemic test and EMG...I have  had chronic shoulder and ankle pain and my MRI of my ankle showed three tendon and three ligaments tears with multiple fractures  from old injuries and my shoulder MRI showed three tears in the rotator cuff.

I am now having some muscle twitching and my hand is stiff each day. I am worried this might all be related to ALS

Headed up to a neurologist next ....any idea if this is all tied together because I sure can't move too well.
