I had issues with muscle pain in my legs, had to start CoQ10 (which made a lot of difference) - is that what you are referring to as stress?
What is the liver damage concern?
Mitochondia tend to atrophy due to statins, which a way of saying that they shrivel and die. Stress was my oblique way of saying that. Muscle pain is a symptom. Muscles and liver both rely on a large contingent of mitochondria. Kill too many of then and tissue damage follows.
I tried 3 different stations in 2006. All gave me bad leg cramps and fatigue. Switched doctorscwhen he would not listen and tried to give me a 4th. Found a doctor who listens. Been on niacin and red rice yeast. Lost 15 pounds over the years moderate exercise and cholesterol is 197 with an HDL of 78. BP is fine.
