The causes of pain in the caudal vertebrae are as follows: 1. If trauma is ruled out, the pain in the caudal vertebrae may be caused by prolonged sitting and standing, because the soft tissues around the caudal vertebrae are relatively small, and prolonged sitting and standing can easily lead to repeated local compression, local hypoxia and ischemia, and nerve damage, causing hypoxic and ischemic pain. 2. prolonged compression can also lead to edema and congestion of the surrounding soft tissues, resulting in aseptic inflammation, causing pain in the caudal vertebrae. 3, 3. Tumor diseases and septic infectious diseases of the caudal vertebrae can cause disturbances in the local internal environment, leading to local bone destruction and increased pressure in the caudal vertebrae, resulting in painful symptoms in the caudal vertebrae. 4. Pain in the caudal vertebrae, if caused by trauma, may be due to fracture of the caudal vertebrae and damage to the surrounding soft tissues, resulting in local pain is evident. Therefore, if the tailbone pain is not relieved within a short period of time, you must go to a regular hospital in time to improve the relevant examination and choose a more reasonable treatment method.
