The fistula is still there, but the amount of stuff it emits is so much less. Just before I noticed this, it got inflamed and discharged a bunch of stuff. Then, it started going away (less stuff). Staying away from sugar, processed flour products and eating lots of healthy fats from grass fed animals and eggs from pastured hens has also helped me get rid of other health problems I was getting.
Another thing that I started doing was eating seaweed, which could be another thing that may be helping as well. I think I may have hypothyroidism (I did symptom checkers and it pointed to that), and as long as I eat a TBSP a day my energy levels are way better than before! In fact, the other day I was so tired and felt nauseated, and I think it was due to not eating the seaweed for a few days. I attribute my thyroid problems to dental radiation 2 X a year from age 5 till I was old enough to not go to the dentist anymore in my teens.
So, if you are all having problems with your teeth, I heartily recommend starting to brush with neem bark tooth powder. I got mine from neem tree farms, but they may also sell it in health food stores.
