There is tumor-like formation on the edge of the anus with pain, and the pain is severe below the dentate line.
If one day, a tumor suddenly forms on the edge of the anus and is accompanied by pain, it is most likely that thrombotic external hemorrhoids have formed. Not all external hemorrhoids are painful, only thrombotic external hemorrhoids are particularly painful. Blood blisters on the fingers, probably everyone has experienced, external hemorrhoids are similar to blisters. External hemorrhoids generally do not bleed, but sometimes with defecation hemorrhoids rupture. Although they are external hemorrhoids, they may be hidden in the anus and invisible from the outside. For early detection, you need to separate the anus with your fingers and touch it. If you touch the tumor and pain, it can be considered as an external hemorrhoid. In the past, a swollen lump was touched in a place where nothing had grown. Most patients would think that something was growing in the anus, but the more painful it is as you push inward, it is a characteristic of external hemorrhoids, which is different from internal hemorrhoids and prolapse.
