I also have sinusitus...I have not gone to a specialist yet, although I am sure sometime in the future i might...my doctor in highschool had me on a few different sinus medications, I tried allegra D, clariten D, both with nasal spray, and nothing seemed to be working....
I did find a good way to get through it while you are waiting for a better solution....BROTH...I've been boiling chicken on the bone with garlic and onion, until most of the water is gone, then keep adding more water....I really dont like onions, but if you just keep boiling and boiling the garlic and onion eventually boil down to nothing. Boil it until you get a nice tasty broth, drink a cup before you go to bed, then boil it down to almost nothing again, put in a jar, and refridgerate, and you now have some chicken garlic broth concentrate that you can add water to the next night, boil a little more and drink a cup of.....if you keep doing this at least a few times a week, it really helps your sinuses, and you will wake up feeling better.
