The main manifestation of an ingrown hemorrhoid is severe pain and swelling in the anus. If you have an embedded hemorrhoid, it is usually a stage 4 internal hemorrhoid or a circumferential mixed hemorrhoid, which cannot be retracted by itself due to forceful defecation, and the hemorrhoid falls out of the anus directly and cannot be plugged back in by hand, resulting in obstruction of venous and lymphatic flow around the hemorrhoid and local stasis, leading to severe local pain and edema in the anus. For hemorrhoid impaction, which is an anorectal emergency, you need to go to the hospital immediately to do surgery as soon as possible, because hemorrhoid impaction makes it difficult for patients to sleep and eat, very painful and if it is delayed for a long time will lead to local necrosis, if the local hemorrhoid has necrosis, the color of the hemorrhoid looks black or dark purple, which will affect the function of the anus. Once the hemorrhoid is embedded in the anus, you should go to the hospital as soon as possible for surgery, which takes about an hour and the recovery time after surgery is about a month to almost fully recover.
