After the skin of a thrombosed external hemorrhoid ruptures, small blood clots may be exposed, leading to bleeding. Generally, resting, diet adjustment, and maintaining soft and smooth bowel movements can be effective. Additionally, local use of hemorrhoid creams and suppositories can typically help achieve healing and stop the bleeding. Thrombosed external hemorrhoids often occur after intense physical activity or straining during bowel movements due to the sudden rupture of subcutaneous veins around the anal margin, forming an oval lump. (The use of medications should be carried out under the guidance of a professional doctor.)
