Thanks for the nice replies to my post.
One thing though to clarify, his doctor did not send him to a psychiatrist. He went to a therapist because he feels depressed. She sent him to a psychiatrist (next door to her) because she felt like he needed antidepressants for his depression.
His medical doctor just keeps giving him pain pills, anti inflammatories, muscle relaxers, and sends him to physical therapy, none of which work for his pain (so he says.)
