When there is a break in the perianal skin, ensure that the perianal skin is clean and dry to prevent infection. You can wash the anus with warm water after a bowel movement, and then wipe the perianal water dry. You can apply some ointment, such as Bactrim or Erythromycin ointment, which can play an antibacterial and anti-inflammatory role. You should try to wear loose underwear to prevent friction between the underwear and the broken skin around the anus when walking or moving around, which can cause pain. In addition, you should also pay a little attention to your diet, avoiding too spicy and stimulating foods and fried foods, and increasing the intake of vitamin-rich foods that can promote the healing of broken skin.
