Thrombotic external hemorrhoids often occur due to intense exercise, straining during bowel movements, eating spicy and stimulating foods, or after fatigue. The onset of thrombotic external hemorrhoids is quite sudden, presenting as a round or oval lump under the skin at the edge of the anus during defecation, with the lump being a subcutaneous blood clot formed from subcutaneous bleeding. The treatment method for thrombotic external hemorrhoids is determined by the amount of subcutaneous bleeding. If the diameter of the thrombus is less than 0.5 centimeters, conservative treatment can be chosen, which includes eating more vegetables and fruits to keep bowel movements smooth and applying hemorrhoid creams and suppositories. If the thrombotic external hemorrhoids do not respond to conservative treatment and the thrombus cannot be absorbed and resolved, a thrombotic external hemorrhoid excision procedure may be adopted.
