Bone pain in the anal area is mainly seen in the position of the sciatic node and pain in the tailbone area. In the case of pain in the sciatic nodes, it is mainly due to the fact that there are more muscle attachment points in this area, and strains and injuries can lead to the formation of inflammatory metabolites, which can cause pain by stimulating the peripheral nerves. There is also a bursa in the sciatic tuberosity, which can become inflamed due to prolonged sitting or stimulation, resulting in inflammatory edema of the bursa, which can also be painful. If the pain in the tailbone area, mainly due to the tailbone fascia inflammation, or some muscle attachment points of the position of strain or strain, and sometimes also due to cold, resulting in the accumulation of inflammatory metabolites, which will produce stimulation of the peripheral nerves around the peripheral nerves, there will also be obvious pain.
