After the hemorrhoid nucleus has prolapsed, if it prolapses more, it can lead to an embedded hemorrhoid if the anus is very tight. How long its necrosis will take depends on the blood supply of the hemorrhoid nucleus. If the blood supply of the hemorrhoid prefers, it may take 5 or 6 days before it may necrotize. If the blood supply is low, the anus is tight, and the prolapsed mass is very large, the hemorrhoid is likely to necrotize in 24-48 hours. After the patient has an embedded hemorrhoid, the pain will be very pronounced, and analgesics are not particularly effective, so you need to return the hemorrhoid to the inside of the anus as much as possible under local anesthesia. You can apply paraffin oil to the surface of the hemorrhoid to make the retrieval relatively easy. If it is not possible to return all of them, it is beneficial to return some of them to the inside of the anus. The next step in treatment, surgical removal of the hemorrhoid nucleus if necessary, is usually considered only after the patient has experienced some pain relief and a slight alleviation of symptoms.
