It usually takes me a week of worrying what's wrong to remember what time of the year it is. I don't have any upper respiratory symptoms, just the stomach pain that sometimes can be severe enough to seem like chest pain. When I take antihistamine, Chlortrimeton, the symptoms diminish significantly. My doctor says I'm nuts and did a complete gastric panel, finding nothing wrong. So, I'm sticking with my self-medicating. I know it's not psychosomatic, because I really never think about the allergy season until after I start getting, and worrying about, the stomach symptoms. Just this evening I had my annual, 'You idiot, it's allergic!" epiphany. Have you ever heard of people having gastric allergic reactions to pollen? Thanks.
