Had to wait until Monday to get an appointment with a pain doctor, when went for the appointment, the doctor was on vacation and could only be seen by PA. Patient had seen another pain doctor and got an appointment, did an x-ray of hips and found had a lot of arthritis, for which was scheduled for injection that was for two weeks later.
