The tip of the buttock bone is the human body’s coccyx, and the pain here is mostly considered to be related to fracture, inflammatory stimulation, ligament strain and so on. 1. Fracture of the coccyx: If there is a history of falling and landing on the buttocks, it may cause different degrees of fracture of the coccyx, which compresses the surrounding tissues and causes local pain. 2. Inflammatory stimulation: such as sacrococcygeal fasciitis, bursitis, sacroiliac arthritis, etc., mostly caused by exertion, sedentary, cold and other local aseptic inflammation, thus causing pain in the coccygeal area. 3. Ligament strain: when the soft tissues of the coccyx are strained, injured or cooled, the local inflammatory edema or bruise can stimulate the peripheral nerve endings, thus causing pain. It is recommended that the pain in the coccyx, especially if it is not relieved for a long time, is also due to other reasons, and it is recommended to consult a doctor in time to find out the cause of the pain, and actively target treatment, so as not to delay the condition.
