i just realized that it may be possible my ongoing allergy-like symptoms may be due to a side effect from one or some of medication I've been on. I'm not sure how to figure this out? I've been to 3 different allergist, had all the tests (all negative). Had 3 sinus surgeries (probably unnecessary and check-up reveal all is clear), I've done food elimination diets although allergy tests revealed I have no food allergies. My quality of life is severely impaired. My nose constantly runs and itches, face itches and is sore and dry, my throat is swollen and I have great difficulty swallowing, i constantly snort and have annoying phlegm , and my eyes are so swollen it appears that i've been sucker punched. Left eye is especially sore and both itch constantly. Docs can't help.
