Despite all of those changes, my allergies are getting worse. I'm taking generic OTC Zyrtec and an asthma medication that my doctor prescribed me. I'm also taking Benadryl before bed because I get so itchy.
My new theory is that it's a food. Having changed all the outside-the-body chemicals that I can think of, this is the best option of those remaining. Other options include an allergy to one of my animals, but I'm not getting rid of them, so I'm going to test the food theory first.
Supporting this idea is the observation that directly after I finished eating left-over Indian food this evening, my nose started running and I started coughing. Now, about 40 minutes post-Indian food, I'm getting very itchy in a variety of different places. I haven't changed clothes or done anything that seems likely to have caused an allergy outbreak.
I'm starting a new elimination diet tomorrow. It's going to be a pain in the butt because I'm trying to combine the hypoallergenic diet I tried last time combined with a low salicylate diet. Unfortunately, the two diets are almost entirely non-overlapping. The hypoallergenic diet excludes a lot of things, but most fruits and vegetables are ok. The low salicylate diet excludes most fruits and vegetables, but a lot of other foods are acceptable. I went through and combined both lists and here's my acceptable foods for the next 10 days:
ripe, peeled pears
green (but not yellow) split peas
possibly either sunflower or saffllower oil
As far as I can tell, there are no actual meals that can be made of foods off of this list. My plan is to make rice and beans and then just whine a lot over the next 10 days. If I see an improvement in 10 days, I'll start adding foods back in one at a time to see if there's any effect. If there's no improvement in 10 days, I'm going back in to see the doctor to get better drugs.
