I found this post quite intriguing and had a couple of questions for the poster. I have bilateral facial pain/numbness over last year and a half. Have seen 2 neurologists and told symptoms don't fit the criteria for tn. have been diagnosed with a 'benign malfunction of the central nervous system' (whatever that means)and my GP thinks it's Atypical Facial Pain. Medications haven't worked for me at all. I found the post interesting though as when i was first sought help i had a routine blood test which showed two things, the first being that i have type 2 diabetes and the second was an inflamed liver. Thought i might try to cut out meat altogether for a couple of weeks just to test it out. Is amonia found in fish? Are eggs ok? Am aware that it's not good to cut out protein altogether.
