I used to have allergies spring and fall, just itchy ears, palate but never severe enough for medication. Last march, after the snow melted, usual itchy ears and throat and that developped in full blowned allergies, runny nose or stuffed up. itchy throat. doesn't seem to matter where I am. At work, at home, outside, away on vacation. I can't pinpoint anything making the allergies bad other than dust and wine. Staying away from wine, still allergies. Even going outside, now with the snow, I'll just start sneezing. This makes no sense.

I think you should consult a doctor, I would make you clear that exactly what makes you so allergic. Perhaps this would make some sence for you.
