Thrombosed external hemorrhoids are a clinical type of external hemorrhoids. The main characteristics of the hemorrhoid nucleus in thrombosed external hemorrhoids are that the hemorrhoid nucleus is stuck at the anus and cannot retract, accompanied by swelling and enlargement. As the hemorrhoid nucleus contains thrombosis, its color is mostly purplish red or dark red, and patients will experience severe local pain and a sensation of distension. Thrombosed external hemorrhoids generally belong to the acute phase of external hemorrhoids, often occurring when the stool is dry or the intestinal heat is severe. For the treatment of thrombosed external hemorrhoids, one can choose Chinese herbal solution for hot compresses to promote the absorption of the thrombus, or directly perform a surgical excision.
