A cold nerve in the neck. The pain is not strong, but I am a taxi driver, I have to turn my head, and I can't. Someone went out and a girl sat down for lunch. Seeing my reckless turns, I began to ask what and how. He suddenly asked to stop the car. The customer’s wish is the law. He takes me out, slightly presses on some points on the neck and neck, and the pain has retreated! To my surprise, she replied that she was a veterinarian, and so horses are rescued.
