For tailbone fractures, the edema of the surrounding tissues and periosteum usually reaches its peak within 3-7 days after the fracture, strongly stimulating the nerve endings to produce severe pain, and it takes about 3 months to recover better. However, there are many patients who may have various degrees of sequelae, such as local pain easily caused by prolonged sitting, and local discomfort in rainy weather. Tailbone fracture is a more common type of fracture in clinical practice, mostly caused by trauma, such as falling on the hip after a fall and a severe impact on the tailbone, which can easily lead to tailbone fracture, thus leading to damage of local continuity and integrity, and producing some inflammatory cytokines, such as prostaglandin factor and tumor necrosis factor, which can stimulate the peripheral nerves, thus causing local pain and causing local swelling.
