Anal pain is heavier appear this situation should not be nervous, should analyze its causes, common causes are the following: First, there may be perianal abscess. If the patient has diarrhea or constipation, sometimes it will lead to anal gland infection, and then it will spread along the rectum of the anal canal to the surrounding area to form a perianal abscess, which will lead to redness, swelling, heat and pain, making the pain around the anus more severe. Generally, the perianal ultrasound can make a clear diagnosis, and once it is clear that there is an abscess, abscess incision and drainage should be actively performed. Secondly, if the patient is often constipated and has dry stools, it is easy to damage the skin of the anal canal leading to fissures, which will also lead to more pain around the anus when defecating, and the pain is generally cyclical. If the symptoms recur, you should also actively perform anal fissure removal to completely treat the fissure.
