It appears I have oral allergy syndrome. Now, I'm not a hypochondriac, quite the opposite. I steadfastly refuse to believe there's anything wrong with me unless I have unassailable truth. However, over the last 5 years or so, my reactions to certain foods have increased and escalated. I can't ignore them - it's difficult to ignore incessant itching and swelling in your mouth and throat.
I underwent allergy testing as a teenager, little injections of known allergens under your skin. If they swell, you're allergic. I think I was diagnosed with cat and pollen allergies. Allergy immunotherapy was the treatment. I'm pretty sure it didn't work, because I'm still allergic to my cat, as well as most green growing things, especially ones with flowers. Thank God my cat doesn't flower.
Then in my late 20s, I started having food allergies. Avocado, cantaloupe, walnuts, pineapple, watermelon. Who in the hell is allergic to watermelon? It's mostly water, for God's sake! But, yeah, lucky me.
Damn conformational epitopes.
