Any HN folks with undiagnosed diseases?

I've been suffering from a condition since around 2014 perhaps longer, that seemingly started after taking antibiotics (ciprofloxacin, Rocephin, Fosfomycin) where my body just loses tolerance to everything I continually ingest. What that looks like is something like an allergy, but my IgE testing on foods is all normal. For years doctors told me I was having panic attacks when I ate which seriously pissed me off. I started going to higher competence medical institutions and they did some testing during a reaction and low and behold one of the times they tested (for some reason only once...) the levels of PGD2 some allergy chemical were multiple times the upper limit of normal. So they thought maybe I have some kind of allergic disorder. They gave me steroids and antihistamines and it seemed to help. however, it only helped temporarily. Fast forward through me almost dying and being hospitalized with malnutrition repeatedly and spontaneously getting somewhat better years later, and I'm where I'm at now. I collect disability, but I suspect they're going to try to kick me off of it now that I'm doing somewhat better. The thing is, the reactions are totally unpredictable except just…
