as to surgery,,,,,,and blood vessels,,it may be ammonia gets trapped at that junction,,concentrated....as i have said,,in bilatteral tn,,,its absolutely imposible,to have two blood vessels trapping a nerve at the same time ,,,people getting double mvd,,are truley wasting their time,,the brain is the problem,not the nerve,,we have had these nerves in our face since we were born,,and all of a sudden,they dont work properly now,,,so what has changed,,,nerve is unchanged,brain unchanged,,,brain chemistry,,,,thats changed,,,you cant see ammonia in a mri scan,,,,this is the question i pose,,,when i can induce tn,and then elliminate it,,,at will,, i am doing somthing few others have ever done,,,and who would ever have thought food was the cause of tn,,,not in a million years,,,not any doctor,,,i got lucky,,,,i got it right,,,after years of tn,and its pain,,the thought of taking those meds again,that made me so sick,,
