The most acute brain shit responded beautifully to 9 months of high dose IV steroids, thank God. The rest of the shit, I have a patchwork of treatments that have improved my symptoms enough to keep me minimally functional, but not back to where I was before all this happened. (Tl;dr - in addition to autoimmune encephalitis, I jokingly call it hipster Long Covid. I got "Long Covid" before Covid was cool, aka ME/CFS)
Mayo is definitely one of the right places for you to go. Just keep hammering on it.
OP spam posts every negative story they find about India. They are not a healthy person.
