I've got Chronic Fatigue Syndrome with PEM from Covid+... ended up Long Covid.
I'm on Low Dose Naltrexone - liquid 4.5mg to help with CFS/Long Covid/pots and PEM - post-exertional malaise + exercise intolerance.
The LDN will help with energy/pains etc, but it is very very slow process to slowly increase the doses as it takes months for LDN to work esp starting it very very low dose ie 0.100mg.
There's no treatment for PEM.. so do rest a lot and pace - don't push yourself too much.
I have been taking vitamin D supplements and a multivitamin with iron, these probably take time to have any notable effect.
I have also had covid a couple of times and long covid did cross my mind. I am currently not on statins but didn't specify this so thank you for the post.
I have a GP appointment on Friday so hopefully I can get a blood test done
