I have had halitosis since the age of 12. I have had my tonsils and adenoids removed as well as an ethmoidectomy. I have had several tests to check for allergies/food intolerance, H Pylori, kidney and liver function, TMAU, Diabetes, Thyroid, Hormones, etc and all clear. I eat healthy and regularly exercise. I had ear infections as a child and ocassional swelling of the eye but no longer. Steroid nose drops/sprays and antibiotics do not work for me. I have seen several ENT Doctors and all say my CT scans are all clear with no deviated septum/polyps etc. I am lactose intolerant so do not have lactose. This is ruining my life. Please help?
