If you are only having external hemorrhoid surgery, local anesthesia is fine. Local anesthesia is an anesthetic around the external hemorrhoid, which can have the effect of anesthesia, because it is not necessary to hold the anus open for external hemorrhoid surgery, and no special muscle relaxation is needed, as long as it is not painful. External hemorrhoids are hemorrhoids that grow below the dentate line of the anus and are covered by the skin of the anus, as long as they are primarily painful. External hemorrhoids often manifest as edema of the external hemorrhoid, which can lead to anal swelling, pain, and if the edema is particularly severe, can cause the patient to fidget. If you are only performing surgery on external hemorrhoids, you will have an external hemorrhoidectomy, which can be done with only local anesthesia, and after the anesthetic is injected around the external hemorrhoid, you can be assured that the external hemorrhoid surgery will be painless.
