Regularly, to prevent such problems coming up, i take Telfast. It helps with eyes, sinus, hives, etc.
Check out (or get someone else to do it for you) the herbal tablets available. I find Echinacea (tablets) [i use 'BIO-ORGANICS' 10,000 Complex], and Hypericum (tablets) [i use 'Natural Nutrition' Hypericum 200 + Ltyrosine] very helpful. Even Garlic (odourless!

) tablets help. -because the stress of the allergy symptoms on the body is much like cold/flu.
There are many more things available though.
I'm sorry you are feeling so rotten, and i hope you get better asap!
