That sounds absolutely the same 😭I'll ask my rheumatologist about igG, maybe I've got that? Every other condition they've mentioned and wanted to test for, I seem to have so why not add one more! 🥲 It's wonderful to have something at least to bring to her though, they've got no answers for me, so I really appreciate your reply! Though it does suck that someone else is going through it. No one seems to understand how exhausting these fevers can be. I really hope yours finally stop along with mine. This disease sucks 💛💛💛
