Summary
A man in his 30s developed long COVID in September 2020 after a more severe reinfection, having had a February infection; he called himself one of the worst cases, with POTS, neuropathy, MCAS, dryness and gut problems. Steroids and antibiotics gave temporary relief, and he improved to 80-90% by March 2022. By 2026 he reported near-complete remission on a strict carnivore diet with ascorbic acid, plus famotidine and a PPI for gastritis and MCAS.
