Hi, Laurin. I'm so sorry to hear about your son's TN. I, too, have a ten year old son and it would be extremely difficult to watch him endure this type of pain. I'm sure your heart is aching.

My heart goes out to you and I hope you are able to find some relief for him.
*edit*
I wish you, your son and family all the best and hope that all goes well.
