The formation of thrombosed external hemorrhoids is mainly related to local congestion pressure in the anal area and excessive filling of submucosal blood vessels, especially after the patient abstains from spicy and irritating food, excessive defecation, and excessive fatigue. This condition becomes more prominent. Once thrombosed external hemorrhoids form, they are generally accompanied by the formation of skin tags and internal hemorrhoids in the anal area, and the external hemorrhoids enclose a blood clot. When the blood clot becomes congested or swollen, the patient will experience significant pain or distension. Once thrombosed external hemorrhoids have formed, it is crucial to treat them early to avoid necrosis caused by prolonged and repeated congestion and edema. Treatment options include using local medications for hot compresses or application to alleviate symptoms, or performing surgery to excise and remove the blood clots.
