OMG I feel for you....I battle sinus all the time. a friend explained to me once about irrigation with salt water, which seems to help.Here's a couple links of info on it :

My friend told me her dr. told her to mix the salt water in a cup, pour it into her cupped hand,and 'snuff' it up her nose,and spit it out. Gross, I know, but when you're desperate! lol I think the neti cups would probably be better.
I have started using some natural stuff from a company,
www.1800homeopathy.com and it seems to really help with the congestion. This co. is awesome...I have used their products for a couple other health problems and they worked great.
My dr. also had me try MucinexD (you have to sign for it here)..said to use that, advil or something for inflammation of mucus membranes, drink lots of water (we all should anyway) and have ample humidity in your surroundings. These things do help I believe. The Mucinex worked pretty well for me but I just wanted to find something natural since I need it so often.
