The symptoms of internal hemorrhoids mainly include blood in the stool, pain, itching and prolapsed nucleus of hemorrhoids, of which there are no obvious performance symptoms in the early stage of the disease. The symptoms of bleeding in the stool, pain, and even anal eczema can occur as the nucleus forms.1. The symptoms of blood in the stool are often painless, manifesting as dripping blood after the stool, and a few present as jet bleeding.2. The phenomenon of prolapsed nucleus, when internal hemorrhoids are found to be moderate or above, the nucleus will prolapse from the anus during defecation, and can be dragged back by hand in most cases.3. The main reason for this is that when the hemorrhoid nucleus is prolapsed, it brings out mucus and secretions in the intestinal tract, which can cause long-term stimulation to the skin around the anus, eventually forming anal eczema and causing itchy symptoms, and when internal hemorrhoids are combined with thrombosis, painful symptoms can occur.
