I have the same problem. If it's the result of a sinus infection or an ear infection then you can do something about it. Otherwise, it's just something that you're going to have to live with. I've seen an ENT on two occasions, but there's really nothing they can do, except for put you on nasal sprays that aren't supposed to be used for PND. So, don't bother wasting your time on those. There's something that I can suggest for you, it's a drug-free nasal spray called STERIMAR. It's not a cure, but it helps a lot.
