Thrombosed external hemorrhoids are usually difficult to heal on their own in the clinic, and most are treated surgically to achieve an effective cure. Thrombosed external hemorrhoids are a relatively common and serious type of hemorrhoid in the clinic, causing redness, pain and, in severe cases, bleeding due to the formation of more blood clots in the nucleus of the hemorrhoid. Therefore, the thrombosed external hemorrhoids must be given high attention, and when found, they must be seen in hospital in time to be treated thoroughly through emergency surgery or surgical ligation or trapping, which can ensure that the thrombosed external hemorrhoids achieve a therapeutic effect that can significantly reduce pain and prevent the thrombosed external hemorrhoids from continuing to deteriorate and causing local necrosis.
