This remedy is very useful for hemorrhoids, which is usually a very common disease; and here you have a feeling of constriction, whether the piles are external or blunt, and sometimes it’s a beating or a throbbing or, as the patient might describe, the feeling of “little hammers” hitting the rectum.
