My worst inhalant allergies are in early spring.. tree pollen.

When I was in my mid twenties I had desensitization for tree/grass/mold.
It worked pretty well. But I still get burning eyes from tree pollen.

Over the years I have developed some allergies to drug dust. These are impossible to control. Augmentin is impossible for me to reconstitute now.
I've had one full blown attack necessitating going home from Augmentin. Sulfonamide drugs also set me off.

This is an occupational hazard, and cannot be avoided 100%. This spring has been pretty bad for me too since the pollen then is additive to the occupational exposures. I am using Singulair now with good success. It seems better than antihistamines.

I did some elimination diets last spring, for my arthritis. Now I am orange free.
Seems that oranges/juice were flaring my knees. I also discovered an intolerance to onions. I used to use them heavily... but now no more. My reactions are mostly GI.
