Dry stool with blood and pain may be caused by anal fissures. Dry stool can easily damage the skin of the anal canal and lead to fissures that are painful and bleeding when straining or defecating, usually with blood on the surface of the stool, and the blood does not mix with the stool. If the symptoms are not particularly severe, the condition should be treated conservatively and with medication. First of all, pay attention to the diet, avoid spicy and stimulating foods, avoid drinking a lot of alcohol, drink more water, drink more honey and paraffin oil to promote the smooth discharge of stool and reduce constipation, and assist in enema treatment if necessary. You can take a sitz bath with warm salt water or 1:5000 potassium permanganate solution to promote the healing of anal canal fissures. You can insert hemorrhoid cream inside the anus and then apply hemorrhoid cream around the anus, which can play an anti-inflammatory, anti-swelling and hemostatic role. If the symptoms are particularly severe, with more bleeding, you should promptly perform surgical treatment, such as anal dilation or fissure removal.
