Well since NS is moving on anyway, I'd request a copy of the report & the images, and start looking for a new dr to replace this one..

If you could see the issue on the image that was mentioned in the rad tech report, I would not waste any more time with this dr..obviously he has mentally emotionally moved on already..

Surgeon's often prefer to do surgery, not pain management.
If what he saw was not a sugical issue maybe that was why he acted that way..
But seems like he could have told you that , if something was not in his skill set....
