Warm salt water vinegar nose douche with a 60cc irrigation syringe always make my sinuses feel much better and heal much much quicker no matter what the irritation is viral or bacterial.
I also start eating lots and lots of garlic powder on everything when I come down with anything for the antiseptic qualities. I usually get a loaf of french bread and make garlic toast with lots of butter and garlic with a strip of mozzarella cheese to make the massive amounts of garlic go down a little better. When my sweat smells of garlic I've gotten enough in my system
If I'm feeling achey all over that's the white blood cells trying to fight infection. Chicken broth helps those cells concentrate at the site of the infection instead of general dispersal. Gets rid of that achey all over feeling.
I hardly ever go to the doctor for cold, flu, sinus, bug, whatever and get better in the same time as those going the doctor visit antibiotic route.
The only exception is one time I got an infection in the bone from an abscessed tooth. Took months of antibiotics to get rid of it. I had to endureoff/on sinus and eye infections cause by the bone infection until it was finally over.
