So glad you at least have a probable diagnosis. Nothing worse than just not knowing what’s wrong.
No kidding. It gives you some kind of idea of what to expect and what to know to try.
For all these years of getting advice about what to do, check for leaky gut, probiotics, "don't eat what you react to" (thanks a lot), try this, that, or the other supplement, etc, none of that is going to be effective if it's not addressing the right cause, which it isn't.
If this were really typical IgE mediated allergies, yeah, a lot of that stuff could help. But it's not. It's a waste of time trying to treat a condition that you don't have.
