I have trigeminal neuropathic pain (long story) - Tried two "rounds" of Botox in my face (along 5th branch trigeminal nerve) - I tried this "new TX" even though the study trial was in Brazil on 15 pts. It did not help me. I agree, it set me back and it took a lot of time, prayer and medicine to regain the ground I had lost. I agree with another post - Your "feelings" are probably right. One thing that has helped me tremendously - keep a daily journal. That's been the only way I've been able to justify my "feelings". It will also help you see the progress your son will make. God bless.
