There are two ways (at least that I've found) to clean out one's sinuses using either a store-bought sinus spray or my old fave, garlic...and a cross-country (Vegas to Chicago'll do) flight. Keep in mind that the garlic will likely piss off whoever is sitting in the seat(s) next to you on the plane.
What you'll need:
- Nasal/sinus spray (like Afrin), OR
- A few sections of organic garlic
AND
- One airline ticket for a three-hour flight or longer
For a few days (three or four), use the Afrin, or take some thin slices of garlic and jam 'em up your nose. Change them at least once or twice daily. Your glands and sinuses will start to feel the magic. Drink plenty of water.
Take your plane and enjoy your flight. At your destination, whether it is a hotel or otherwise, be sure to take a long, hot, steamy shower, and blow your nose while doing so.
I was surprised at some of the stuff that came out (and it was stuff that wasn't doing me any good, for sure), and how much better I felt after the works had been cleaned out. The lower pressure of an airliner's cabin (they are pressurized to the level of several thousand feet) can not only make your ears pop, but it can be used to clean out your sinuses as well.
It beats having to pay someone in the healthcare industry for a vacuuming, and doesn't require any health insurance, either.
