I just came across your post - I know it’s been a few years. I had Covid, shingles and Covid again all within one year - and immediate started gaining weight. I’ve been healthy and strong my whole life with a healthy body fat %. After the infections, I started gaining 1-2 pounds a month.

I’ve been down a really long rabbit hole - ME/CFS, POTS, MCAS, Hashimoto’s. All are being treated. A pulmonologist just had me do a diaphragm strength test and I showed weak inhalation - possible from shingles. I’ve had pretty intense muscle pain and tightness in my left shoulder. I didn’t put the two together, but I think it’s related to the nerve affected by shingles (along my bra line and in my armpit).

I do know that the way you exchange oxygen and carbon dioxide can change your metabolism.

I’m wondering if you found a solution and if it lines up at all with what I’m going through?

Thanks!
