Bleeding buttocks pain during stool may be an anal fissure. Dry stool can easily lead to fissures in the skin of the anal canal, which may damage the fissure of the anal fissure and cause pain when defecating, and repeated stimulation of the trauma can lead to bleeding. If the amount of bleeding is not large and the symptoms are mild, you can take conservative and medication treatment, pay attention to your diet, avoid spicy and stimulating foods, and take honey or paraffin oil orally to promote the smooth discharge of stool, which can reduce the stimulation of the fissure wound by stool. You can take a sitz bath with warm salt water or 1:5,000 potassium permanganate solution to promote perianal blood circulation and reduce perianal swelling and blood stagnation. You can apply hemorrhoid cream and hemorrhoid suppositories, and you can apply hemorrhoid cream outside the anus such as Tai Ning Cream, which can be applied to the perianal fissure to play a role in anti-inflammatory, anti-swelling and anti-itching and hemostasis. If the amount of bleeding in the stool is relatively large and the pain in the buttocks is particularly severe, you should promptly perform surgical treatment, which can include anal dilation to reduce the spasm of the internal anal sphincter or anal fissure excision.
