Pustules next to the anus are considered to be perianal abscesses. Perianal abscesses are caused by inflammatory infections, mostly caused by anal sinusitis or anal adenitis. The main symptom of perianal abscess is a lump around the anus, and the pain gradually increases, and some perianal abscesses can break down and flow pus on their own, forming an anal fistula. If a perianal abscess occurs, it should be treated surgically as soon as possible, so as not to delay and delay the condition. If the condition is delayed, sepsis or septicemia can easily occur, which can endanger life. Therefore, when a perianal abscess occurs, it should be treated actively to prevent the inflammation from expanding. In ordinary life, it is important to keep the bowels open and pay attention to the cleaning of the anus. If you find symptoms of anal sinusitis and anal adenitis, you should actively treat them, eat less spicy and stimulating things in your life, and be less sedentary and stand.
