I am no expert in this at all. I know very little. I’m still struggling for a diagnosis myself after 2 years of seeing experts and finally getting Vit B12 deficiency diagnosis by my second neurologist. (First neurologist dropped the ball.) Still…..much is a mystery, however….is there some downside to a functional diagnosis? Can’t it still be treated? It’s real and valid as any other medical condition, right? Maybe, I’m off. I’ve done some reading and watched a couple of documentaries about it. If treatment helps, does it matter the name it’s given? I’m asking because I really am curious. Does insurance still cover treatments?
