I have not been able to breathe through my nose for about a year ...

I have not been able to breathe through my nose for about a year or year and a half. I have tried all of the prescription allergy medications, nasal sprays, etc. None have even remotely worked. Two and a half months ago I ended up with a sinus infection that Augmentin did not help, so I received my first Kenalog shot with a second dose of Augmentin. It was amazing! I could actually breathe through my nose and smell again. It lasted about two months perfectly, until my allergies came back and I ended up with another sinus infection. Today I had my second Kenalog shot and I hope it works as well as the first time. But now I am reading about all of the side effects and wondered if anyone has tried anything else that doesn't involve Kenalog for their allergies.
