Tailbone pain in women is mostly caused by chronic inflammation of the soft tissues in the sacrococcygeal region due to long-term poor sitting and sedentary posture. In addition, pregnancy, inflammation, fracture, developmental abnormalities and other reasons can also lead to bleeding and edema around the patient’s tailbone, and the lesion can compress the nerve endings around the tailbone, resulting in pain in the tailbone, lower end of the sacrum and surrounding tissues: I. External factors 1. congenital malformation: for example, when a woman is born, the presence of forceps assisted delivery or breech delivery can cause damage to the sacrococcygeal area, and subsequent pain in the female tailbone may also occur; 2. special Time: during pregnancy, with the gradual increase of the fetus, the caudal vertebrae may be compressed by the uterus, local congestion, resulting in pain in the caudal vertebrae, usually the symptoms will gradually disappear after delivery; at the same time, obstructed labor can cause damage to the sacrococcygeal joint of pregnant women, which can lead to pain in the caudal vertebrae of women; 3, age factors: the growth of age and the accumulation of injuries may cause degenerative changes in the body, or sedentary women in offices, heavy labor, drivers and other female groups. The female groups, such as physical labor and drivers, may induce female coccyx pain. Second, the lesion factors 1, trauma: female hip impact injuries, falls, etc., may damage the sacrococcygeal ligament, or even lead to tailbone fracture, dislocation, etc., resulting in women produce severe pain in the tailbone area; 2, neuropathy: mostly seen in the lumbar spine disease caused by continuous pressure on the nerve, resulting in continuous radiation-like pain symptoms in the tailbone. Such as lumbar disc herniation, in addition to women’s tailbone pain, but also accompanied by back pain, lower limb pain and other symptoms; 3, inflammatory lesions: such as inflammation of the ligaments and fascia at the tailbone, osteoarthritis of the sacrococcygeal joint, sacral neuritis, and inflammation of the reproductive system can stimulate the tailbone nerve, triggering tailbone pain; 4, other: relatively rare, such as chondrosarcoma, chondrosarcoma, etc., can compress the nerves and blood vessels around the tailbone, resulting in pain. Pain can occur. Therefore, it is recommended that women who experience pain in the caudal vertebrae should seek medical advice to identify the cause after rest is not effective.
