Caudalgia can be characterized by caudal pressure and abnormal activity on anal palpation, and sometimes the fracture end and displacement can be palpated. Depending on the cause of the disease, the pain may be caused by the dislocation of the caudal fracture, as the distal end of the fracture is displaced forward or laterally by the pulling of the caudal muscle and the anal levator muscle. The pain is lighter when standing still or lying down, and it increases when sitting or straining in stool; and there is localized pressure pain. There may be caudal pressure and abnormal activity on anal palpation, and sometimes the fractured end and displacement may be palpable. Most of the symptoms are milder when caused by other reasons, especially in congenital and long-standing cases. Patients with tailbone pressure pain and abnormal activity should avoid eating greasy food; avoid eating spicy and stimulating food. Fatty meat: Fatty meat contains more fat and is not good for fracture recovery. Try to eat less or not to eat. Doughnuts: contain a variety of chemicals harmful to the body. It is recommended not to smoke. Chili pepper: it is easy to stimulate gastrointestinal discomfort and lead to malabsorption of nutrients in the stomach and intestines, which affects the absorption of nutrients and the recovery of fractures. So try to avoid it.
