When a mixed hemorrhoid becomes protruding and embedded, the blood supply in the nucleus is affected, which leads to ischemic necrosis of the nucleus. The ischemic necrosis of the hemorrhoid will produce severe pain, and the surface color of the hemorrhoid nucleus will turn gray, accompanied by erosion and exudation of the entire nucleus. If the hemorrhoid nucleus prolapses and shows signs of necrosis, the nucleus should be dragged into the anus in time so that the nucleus can regain some of its blood circulation, thus reducing the symptoms of necrosis. In addition, clinical attention needs to be paid to some patients with diabetes, who have a poor ability to resist infection. When there is local necrosis of the hemorrhoid nucleus, the infection may quickly spread to the perianal tissues, causing necrotizing fasciitis and even life-threatening. So when the hemorrhoid nucleus becomes embedded and edematous, you should go to the hospital in time to prevent serious complications.
