My two biggest allergies are to medicines with Ceclor and Sulfa drugs in them.
I'm not sure which one it is but one of those will cause a red ring to appear around my neck and i get to where i cant breath (which last time it happened resulted in an ambulance ride), as the other it simply makes me break out.
The only other allergies i have are seasonal with them being their worst during spring and summer when pollen is about, though the weird thing about my seasonal allergies is that they only affect me in my home state if i were to visit another state in any direction its like i practically have none at all.
I'm also allergic to hornet stings.
Also oddly enough I'm immune to poison ivy/oak lol.
