In general, the first thing to consider when a pimple the size of a soybean appears in the anus is a high probability of hemorrhoids. If it grows around the outside of the anus, it is more likely to be an external hemorrhoid. If it is inside the anus and will protrude when defecating, but can be returned on its own, it is mostly a mixed or internal hemorrhoid. If there is no special discomfort, you can observe it for the time being and do not need special treatment. Pay attention to your diet, avoid sitting for a long time, and do more anal lifting exercises. If there is pain, blood in the stool or if the hemorrhoid cannot be retracted after prolapse, symptomatic treatment is needed. The actual piles can be cleaned after defecation, pay attention to local hygiene, take a sitz bath with potassium permanganate solution every night, apply Ma Yinglong hemorrhoid cream or hemorrhoid suppository to the anus, take Sophora pill orally, eat more vegetables and fruits, and avoid spicy and greasy food. If you do not see significant improvement after the above treatment, it is recommended to go to the anorectal department of the hospital for surgical removal and regular change of medication after surgery to avoid infection.
