Chronic bad taste and breath

I have had chronic bad taste and breath for the past 10 years and I am at a complete lost.

I have seen several gastroentrologist along with ENT doctors over the years.  I have had cat scans for my sinus along with an endroscpy several of them and each time the results are negative.  I get my teeth cleaned every 6 months and my Dentist says all is okay. The bad taste is 7-24 and never goes away along with the bad breath.  My live is horrible, very anti-social.

What should I do, where should I go for help.

Hi Big,
Are there any other symptoms, like excessive phlegm in the back of the throat? Do you find yourself coughing up tonsiliths (little yellow stones that smell gross when crushed!)?

Have you seen any breath specialists? They can take a reading of your breath and work out what type of bacteria/compounds breaking down that could be causing your bad breath. Other than that, search the web! You'd be surprised by how many people share this problem.

Good luck!
