Try AXA1125 (BCAA + Glutamine + NAC + Arginine) for mitochondrial dysfunction. The regimen consisting of 400mg DCA + 100mg B1 Hcl + CoQ10 and Acetyl L-Carnitine got 45% of ME/CFS patients back on track (55% had other comorbidities that interferred with the effect) in some study. Lactoferrin + Iron (bisglycinate/liposomal) and diphenhydramine could help restoring gut and alleviate neurological issues from spike protein. I battled it for 2.5 years as well, people have no idea how bad it could be (felt like I was 90 year old just before death). The only remaining symptom now is occasional severe vertigo in raining weather. Good luck!
Spike protein looks like iron transport inhibitor hepcidin (discovered fairly recently) and it's speculated it inhibits iron uptake by cells and prevents cells from moving excess iron out so one could end up with cellular-level anemia or its opposite. Lactoferrin regulates cell iron, acting as a homeostasis agent and I added more iron as my hemoglobin was around the bottom of the normal range.
Take care - I hope you get to improve. My wife got covid back in March 2020 and was pretty ill, then fell into full long covid (back before anyone knew what it was). She was totally wiped out (I have posts on my account detailing it if you are interested), but is finally back working and living again - so please know the recovery is possible for some. She's still not where she'd like to be, but is vastly improved from her worst.
Unfortunately she has had it 3 more times since the first, but lucky they have passed her fairly smoothly. On my more recent infection I've started to get joint pain on my left side - which is fun - I'm only 43 and suddenly see why old people wince when they get up or climb down something. Sure will pass, but this virus sure is weird.
Lemme put it this way. It highly resembles fibromyalgia. Most doctors in America won't recognize fibromyalgia because in a lot of cases there is no treatment and there is no way in hell industry is going to adapt to having sick people in it, nor is disability going to recognize it. Even if they did recognize it the US disability system is a lot closer to eugenics then it is a social service.
Stay safe out there. We have to work together to help each other out on this one and related matters.
It's a pretty dumb life move to collect disability if you don't need it. I mean, you are condemning yourself to poverty and being one bad thing away from death.
Crohns is diagnosed via a biopsy iirc, it's not a diagnosis of exclusion like IBS is. Crohns is also horrific. so I wonder if you just view your friends poor health as a typical "no one wants to work anymore" way like most people do with disabled people. Fibromyalgia is somewhat a diagnosis of exclusion, but decent doctors can mostly figure it out these days. The hard thing is discerning whether it's ME CFS or not.
