Tailbone cysts are generally referred to as tailbone cysts. Symptoms of tailbone cysts are related to the size of the cyst and whether the surrounding tissues and nerves are compressed. Smaller cysts usually have no special discomfort, while larger cysts that compress the surrounding tissues and nerves may cause pain, sitting tenderness and other discomforts. Tailbone cysts are benign lesions. Small cysts usually have no special discomfort and are usually detected during a physical examination. The main concern is to observe changes in the cyst, and if there are no changes for a long period of time, no special treatment is needed. If the cyst is large, it may compress the surrounding muscle tissues and nerves, which may cause localized pain, perineal pain, and pain aggravated by compression of the cyst while sitting, which may require surgical resection. If there is any discomfort in the caudal cyst, go to the regular hospital for consultation, and the doctor will judge whether the discomfort is caused by the caudal cyst according to the symptoms, signs and auxiliary examination, so as to give the correct treatment.
