I hae allergies. My eyes were badly inflamed last night, and my eyes were burning. They're burning today as well.
Actually, the discomfort has subsided a bit, now that I'm in an airconditioned room. Still, this whole situation stinks.
It's a problem with allergies, which makes it an immunological problem. Basically, allergens trigger an undesirable immune system response. An allergen is a type of antigen that create a spurious immune response; that is, they aren't toxics or pathogens, but they make the immune system respond anyway. Argh.
