I have had this sinus infection for exactly 1 month tomorrow :( I never had a sinus problem before...except I think 1 time and that was following a bad cold.
This time round, i had no cold or nothing. Just a horrible pain on the right side of my head. It affected my ears throat teeth cheek everything on the right. I had a horrible taste and even smell in my nose. Anyway so first I thought it was tooth problem. But the dentist diagnosed sinus and gave me antibiotic. It was bit better but not by too much. Next ENT specialist told me is a very bad infection. More antibiotics, decongestants and nose drops. Ugh! Ok by yesterday about 80% cleared, but still not quite.
Then I was told about a method, similar to netti pot. Fill a glass with warm salt water. Fill syringe with the water and squirt into each nostril while bending over a sink. The water will go in up the nasal cavity and flow out immediately. I experienced a lot of relief from this method. But have to keep at it for a while.
Hope it clears out completely.
