Chronic pain: after the tailbone fracture, due to poor alignment, displacement, fascial injury, etc., chronic pain, and then intractable pain, mostly aggravated when sitting for a long time, bending over. 3. Injury to the surrounding organs: If the rectum is compressed after the tailbone fracture, symptoms such as difficulty in defecation and constipation will occur. If the bladder is damaged, incontinence may occur at a later stage. Women with severe tailbone fracture may damage the birth canal, affecting the subsequent normal birth.
