bad smell in nose

[lilisun]

I  constantly have mucus running down the back of my throat. The mucus itself is fairly tasteless. However, I have a foul taste and smell in my nose constantly, and most foods I consume are adopting that taste/smell.
There is no blockage anywhere, and no pain.
I  had all sorts of tests done and also saw a specialist. No one can find anything wrong.
Does anybody out there have a solution?

Frenzel technique for clearing mucus out too

[Charlimi]

Look up Frenzel technique. See if you can blow air out of your nose only, with your mouth open. Can you do it lying down? Can you puff up your cheeks with air then send that sir out your nose only? Work on doing these things and you may eliminate getting food up into your sinuses.
