I am allergic to many things, far too many to mention (and with strange Latin names no less). I don't know everything I'm allergic to but on my last allergy testing which looked at about ~50 different potential allergens, I was allergic to all but 7 of them. I have indoor year-round allergies (including cats-- though I still have them!, dust mites, mold, tobacco smoke, etc.) and seasonal allergies, both spring and fall (trees, pollens, grasses, you name it).
No obvious food allergies, but that's not to say they don't exist. But it does seem that my sinuses are more allergically reactive than other parts of my person.
I'm definitely not allergic to penicillin though, thank Bob. With constant inner ear infections for the first two years of my life, I LIVED on amoxcillin.
