Tearing pain in the anus when relieving stool, accompanied by blood in the stool, is a typical clinical manifestation of anal fissure. Most anal fissures are caused by excessively dry and hard stools that cut the skin of the anal canal, thus causing anal tears. First of all, you should soften the stool, you can take Chinese medicine such as Maren Pill or Sophora Pill to lax the bowels and open the bowels. The second thing you need to do is to take a sitz bath with warm water or potassium permanganate water to improve the blood circulation around the anus, which can also reduce pain. Also pay attention to a light diet and avoid spicy and stimulating foods as well as fried and deep-fried foods. Most of the early fresh fissures can be cured in about 7-10 days by the above treatment plan.
