Some internal hemorrhoids that prolapse can retract on their own, corresponding to second-degree internal hemorrhoids. If manual repositioning is required, these are typically third-degree or fourth-degree internal hemorrhoids. Third-degree internal hemorrhoids need to be manually repositioned because the external anal sphincter obstructs the retraction of the hemorrhoids. Generally, the method of taking a warm water sitz bath is used to relax the external anal sphincter, after which the hemorrhoids can be manually repositioned. During repositioning, applying some paraffin oil can facilitate the process, making it easier to accomplish.
