What are your thoughts of Lipitor and my constantly and recurring physical degradation?

My history is as follows:
In 2012 I had a heart attack at 85 years of a physically active life including home remodels and regular exercise.

Maintenance prescriptions included Lipitor, Carvedelol, Lisiniprol, Effient, and Aspirin.

I finished cardiac rehab at the end of 2012.
3 or 4 months after rehab while continuing my daily exercises I started feeling weak.
Within 3 days I got so weak I could not walk, lift 3 pound dumbbell weights, or stand up.
Went to emergency to run some diagnostics to determine my physical degradation.
My concerns were that Lipitor was causing my weakness. Kidney functioning tests did not show signs of muscular disintegration.

Therapy after this occurrence brought my strength back to mobility with a walker.

This cycle has occurred another 4 times till just recently and I can never regain strength as before each hospital return visit.
