A fall down the stairs resulting in tailbone pain can be caused by two possible causes. The first cause is a relatively minor injury, which is a soft tissue injury to the sacrococcygeal area, including damage to the superficial fascia of the skin as well as the ligaments. As a result of falling down the stairs, the sacrococcygeal area will be subjected to some violence, so it will lead to local damage, which will then cause local pain. The second reason is that if the degree of injury is more serious, the force suffered is greater, and in serious cases, it can also lead to tailbone fracture. At this time, you should go to the hospital to take a positive and lateral X-ray of the tailbone to determine if the tailbone pain is due to a tailbone fracture. However, whether it is a soft tissue injury or a tailbone fracture, the vast majority will only require conservative treatment.
