The most important cause of radiating pain in the anus is nerve pain. There are different types and numbers of nerves distributed throughout the body, and the same is true for the anal area. Among them, the cauda equina is a very important nerve located below the conus of the spinal cord. Some people can compress the cauda equina nerve due to prolonged sitting and squatting, causing radioactive pain in the anal area. In this case, it usually does not cause other lesions and mostly only shows painful symptoms. It is recommended to increase the amount of daily activities in moderation and avoid maintaining and using the same posture for too long. Strengthen physical exercise, you can do more anal lifting exercises. Use warm water for local anal sitz baths to increase the local venous blood return to the anus and speed up the blood circulation rate, and in most cases the symptoms will be relieved by themselves. If the symptoms are not relieved or recur after a period of time, it is recommended to go to the hospital for relevant examinations and symptomatic treatment.
