I have been to a GP, 2 Dermatologists with subspecialties, and 2 internists and all of them didn’t know a damned thing . How to dx, what test to order etc. one dermatologist scraped my skin to see if I had systemic candida. It wasn’t until I saw a physician that specialized in infectious diseases was I finally told that It Wasn’t All In My Head, it was in my blood. So i suggest the first physician to see would be an infectious disease specialist, they commonly treat patients with HIV who almost always have candida because of their compromised immune system.
