You can try homeopathic (I'm not sure if I spelled it right... or if it's even the right word

my English is not completely perfect) stuff. It's a kind of natural treatment, I think you can find it at a drugstore. They make homeopathic medication for almost every health problem. I have used the one that cures the runny, clogged, irritated nose, if I remember the name of the treatment is Coryzalia or something. Some people say it doesn't work, but for me it works extremely well.
I hope I helped you, I'm afraid that what I wrote is more confusing than anything... I have to go to sleep now, writing stuff like this makes me tired... I have a job interview tomorrow morning so I really don't want to stare at my screen all night and act all weird tomorrow. I want to work so I can have money and go buy things
