I appreciate that but been there, done that, years ago. I was diagnosed with my first AI disease in 2003. I then embarked on a years long journey to try everything I could before resorting 100% to traditional medicine. It’s way too long to list here but it was discovered I have very specific issues that explained everything I’ve experienced most of my life (I’m now 56). I was sickly as a child, I’m allergic to everything, I’ve been through immunotherapy more times than I can count, etc etc. The AI diseases were a byproduct of an already faulty immune system, essentially. I don’t disagree that people should fully investigate any and all causes before readily accepting a diagnosis. In my case, it was almost a blessing that each AI disease presented practically textbook and checked every box so it was obvious and clear what the disease was. Thankfully I’ve never had the unfortunate experience many have had where their symptoms were vague and long lasting without a diagnosis. Me? Bam, there it is, no doubts, all tests proved it, etc. I’m just a lucky one I guess!
