What causes this disorder and how can we fix it? I am getting severe tinnitus triggered by foods I have eaten all my life. More and more things trigger neural inflammation every day. My mouth and hands become numb and I feel highly anxious. I am unable to sleep, highly irritable, and feel crazy! I have been gobbling antihistamines by the truckload with no help. High dose b12 helps for like 5 minutes and then the ringing is back! What is this?!?
