Well, I went and got tested for allergies and it turns out that I have a pretty severe cat allergy. Symptoms include ear congestion, sinus pressure, swelling of lymph nodes, etc. The rating scale basically breaks down into 0-5 with 0 being no allergy and 5 being the most severe allergy. I'm a 4/5 for cats. I also had 2/5 for dog, dust, marsh elder, and pigweed.
I don't have any of the typical symptoms you think of for animal allergies (itchy skin, watery eyes, runny nose, sneezing, etc), just these odd-ball ones.
Anyway, I'm going to start getting allergy shots that should clear it up or at least make a significant difference. It takes about 6 months of 1 shot/week to build up your resistance to the allergens, but I've been trying to figure out what is wrong with me for 2 years so this is great news! I no longer worry that I have something seriously wrong with me!
