The clinical manifestations of anal fissures, also called anal fissures, are mainly bleeding, anal pain and constipation. You can choose to use hemorrhoid ointment, such as Ma Yinglong hemorrhoid cream or anal tide ointment, to apply on the fissure area to stop bleeding and pain treatment. Of course, if the anal pain is severe after a bowel movement, you can take a sitz bath in warm water to relieve the spasm of the anal sphincter and relieve the pain, and if necessary, you can also incorporate diclofenac sodium suppositories into the anus for pain relief. The most critical thing is to soften the stool, if the stool is too dry, it will repeatedly stimulate the fissure resulting in difficulty in healing. The diet should be light and avoid spicy and stimulating foods.
