The choice of medication for external hemorrhoids is determined by the symptoms. External hemorrhoids are divided into varicose external hemorrhoids, connective tissue external hemorrhoids, thrombosed external hemorrhoids and inflammatory external hemorrhoids, of which varicose external hemorrhoids and inflammatory external hemorrhoids are mainly treated conservatively, for example, when the nucleus of the hemorrhoid appears to be locally itchy you can use potassium permanganate solution with a sitz bath at a ratio of 1:5000 by mass, and local eczema can be treated topically with Dinaide cream. When the hemorrhoid nucleus is locally swollen and painful with edema, you can take oral Diosmin tablets or elimination tablets and use topical Ma Yinglong hemorrhoid cream with warm water sitz baths to reduce the swelling and treat the symptoms. The main clinical treatment for thrombosed external hemorrhoids is surgery, which can be performed by thrombectomy or thrombosed external hemorrhoidectomy. Some thrombosed external hemorrhoids that are not very symptomatic can also be treated conservatively with medications, such as oral Diosmin tablets or anti-depressant tablets and topical Ma Yinglong hemorrhoid cream. It is important to note that normal external hemorrhoids without clinical manifestations do not require any medication, even if the use of medication is to control the symptoms and does not make the external hemorrhoids disappear. The patient should usually pay attention to a light diet, keep the bowels open, and pay special attention to the cleanliness of the anal area after the bowel movement.
