Re: sinus infection
The BEST treatment ever is Neti-Pot. You rinse out your sinus cavities with a warm saline solution and wow! Does it EVER work! Local pharmacies should all carry them, you use it 2 or 3 times a day and even if its a bacterial infection, you can sometimes avoid going the antibiotic route, it worked for me that way a couple of times.
Hope you feel better soon!!
