Michael has arrived for his second visit near the end of the days office hours. He does not have an appointment, but claims to be suffering from extreme back pain. On his last visit he was given a prescription for an opioid analgesic. He says that he is new to the area, his records from his previous physician have not arrived at your office, and when asked for contact information, he promises instead to contact the office himself when he gets home. How would you handle this situation?
