Imagine that you are a psychiatrist and a patient comes to you by referral. His other doctors can't figure out what's wrong with him. He has a long list of symptoms including chronic leg and back pain, rage, depression, irritability, inability to concentrate or make eye contact, insomnia, alcoholism, gastritis, hypertension, and much more. Things started with just a mild case of foot pain but became gradually worse over the past year. The man only seems coherent when he is sitting down. When he gets up to walk he becomes increasingly more agitated and downright violent. He is angry at his pain. He drinks at night just to sleep. He has threatened his doctors because they can't fix him. What do you do for this man?
