Bad Breath Halitosis Forum

I have BB and have a sinus infection yet the bb doesnt originate from the nose rather it comes from the mouth. Is there any link I can draw from this. Or is my bb originating from something other than my sinus disease because I've been taking nasal steroids, prednisone and other prescription to no avail in relation to removing my bb.

from what i heard the sinus infection makes you have pnd/ mucus in the throat, this collects on the end of your tongue and this mixes with mouth bacteria and starts producing bad odor.

somewhere on this board its written down more detailed i would guess.
