I Have CFS, I Think. Sleeping Does Not Recharge My

I have CFS, I think. Sleeping does not recharge my batteries, i have trouble getting started and after lunch I HAVE to have a nap. Otherwise I fall over. In addition I have the feeling of "ripped" muscles in both my upper arms (both sides). Could this be caused bt (i) thyroid trouble , or (ii) testosterone shortage ? I am 75 and have been of good health, until 5 years ago, when after I toot a statin, all hell broke loose.
