Sudden onset weakness not better after 3 years

The story of Cory

Athletic, healthy 60+ took statins for 20 years. Sudden weakness and exercise intolerance 2019. Weight bearing exercise at a low level now, losing strength (trouble carrying things, opening things). Many specialists later no help and no diagnosis. Looking into a holistic provider to figure out why my muscles aren’t getting what they need. I have been told it could be a metabolic problem. Living with Fibromyalgia and Hashimoto’s for 30 years but that didn’t stop me from exercising.
