There are more reasons for tailbone pain, which may be caused by physiological reasons, trauma, tailbone fracture, sacral fasciitis, tailbone tumor and so on. 1. Physiological reasons: generally due to less soft tissue around the tailbone, sitting on a hard chair for a long time will lead to localized pressure on the tailbone, which will cause pain. You can put relatively soft cushion on the chair to relieve the pressure on the tailbone. 2. Trauma, tailbone fracture: falling down while walking, hips on the ground or tailbone touching sharp materials, resulting in soft tissue injury to the tailbone, there will be symptoms of tailbone pain, which may be accompanied by redness, swelling, bleeding and other symptoms; if the injury is more serious, resulting in tailbone fracture, the presence of a clear point of pressure and pain in the tailbone area, need to carry out X-ray and CT and other tests, in order to make a definitive diagnosis. 3. Sacral Fasciitis: Due to long-term sedentary tailbone wear and tear, aseptic inflammation of the tailbone, such as sacral fasciitis, etc., the tailbone localized by inflammation stimulation, will produce local pain symptoms, and may be accompanied by redness and swelling of the surrounding skin, elevated skin temperature, need to consult a doctor in time, and conduct relevant examinations for further clarification. 4. Tailbone tumor: if you feel a hard mass at the tailbone, or even the shape of the tailbone changes, it may be caused by the tailbone tumor, which will compress the tumor when sitting down and cause pain in the tailbone, which needs to be further clarified by puncture and imaging examination. When tailbone pain occurs, it is necessary to consult a doctor in time, according to the medical history, clinical symptoms, X-ray and other related imaging examinations to clarify the cause of the disease, and carry out targeted treatment. In addition, it is recommended that patients reduce activities when in pain to avoid aggravation of pain symptoms.
