I have been getting a number of ulcers on my tongue for the past couple weeks and have serious bad breath which my husband says he can smell just with my breathing from my nose.  My oral hygiene is very good and I know that is not the problem.  What are possible causes and should I see a doctor?Also about ten years age I had nissan surgery for a hiatal hernia and the doctor said I have a duct or pocket in my esophagus that could collect food.  I remember him saying if I had bad breath to get that checked.  I dont remember what that was called and can that be my problem?
Thanks for your query, I have gone through your query. The halitosis or bad breath could be because of the deposits causing gum infection or ulcers covered with purulent material or even the pocket in the esophagus. These can accumulate food particles and cause bad breath. Consult an oral physician and ENT surgeon. Get you teeth cleaned. Treat the ulcer with topical anesthetic and analgesics like Anabel gel. Use mouth washes. I hope my answer would help you. Take care
