I am so sorry that I have no solutions. I can tell you I was once put on a very strong old time anti-depressant as they found it reacted with the nerve centers of the spine and would perhaps leave me pain free as long as I was on it. It did relieve the pain but it also relieved any and all of my thoughts and ambitions and most of my brain cells I am sorry to add.

I went on a weaker one which did not help the pain but it helps me cope with the pain. Maybe he is on the wrong anti-depressant?

Blessings,
