Ooof dude that's way above my wheel house. I got basics down but no where near that level of knowledge. I liked your original post cause I tell new Medics the same thing! I did work in a OR for a while and from experience ANA positive is super indicative of autoimmune but any more then that I'm clueless. I'm sorry about all that brother, it insane we know so much and so little that "medical mysteries" still exists. All the best wishes, when you get better here soon, come reply and lmk!
