Breathing Is Terrible

I would suggest, similarly to Quincy, you try a Neti pot for a week and see. But make sure you use boiled water. I have heard stories of people using tap water and getting some parasitic organisms in their brains as a result.

The other thing you can try, is I think it's Vicks, they make a vaporizer, which has a cone-like structure, into which you put your face (apparently some women use it for facials?), and you breathe in vapor - and that's very good at opening up the passage ways. They do sell the mentholated vicks pads, but you dont need to use them to work the machine.

Also, you could try the homeopathic remedy, called Kali Bichromium, which is for congested sinuses, it usually works pretty well.

keep your windows closed.  get one of those air purifier things for your bedroom.  you can try a rx nasal spray.  My son uses veramyst and that seems to help him somewhat. he also uses ocean, which is a saline type solution nose wash, all natural to keep everything moist up there. they do sell homeopathis nose sprays but Im not that familiar with them.  neti pots are may help you.  when ive been clogged with a sinus infection i've used them before with good results.

do you have indoor allergies as well?
