Tailbone protrusion is directly related to congenital tailbone deformity, or tailbone misalignment due to trauma, or tailbone protrusion due to tailbone fracture. Due to the special anatomical structure of the tailbone, it is the part that is most frequently in contact with the stool surface when sitting or standing. If the tailbone protrudes, it will lead to frequent friction between the tailbone and the stool surface, resulting in sterile inflammation, which will lead to tail pain at a later stage, manifesting as a significant stabbing pain in this position of the tailbone, and in severe cases, it may lead to pain and afraid to sit or stand. For this kind of tailbone protrusion, if it is particularly serious, you can consider surgery to remove the protruding part. Usually, you must pay attention to take good care of the tailbone, you can bring soft pads to reduce the direct contact between the tailbone and the stool surface.
