Thrombotic external hemorrhoids are a type of external hemorrhoids. Generally, after 2-3 days, the thrombus begins to be absorbed and the pain significantly reduces and can be healed. However, in cases with a large thrombotic lump, significant pain can occur and in severe cases, it can hinder walking. The patient may be restless whether sitting or lying down, the surface may re-ulcerate, causing bleeding, and the thrombus can naturally expel itself. At this time, the lump will be eliminated.
