get yourself some Nong Shim ramyun spicy picante beef. its not that 10 cent cheap ramen college kids eat, its good stuff. but this stuff is wicked hot! i swear by it now when im sick, esspecially with the sinus and throat infection, its gonna burn double worse BUT! you should feel better later in the day, while your eating it i swear youll feel great (except for the excessive burning in your nose and throat lol) and be able to breathe better for a while.
Whenever I'm sick I'll eat stupidly spicey foods as well. Cleans your sinus's right out and you feel far better afterwards. If the spice is too much, just down a glass of milk afterwards.
