The main symptom of internal hemorrhoids is blood in the stool, and larger internal hemorrhoids with prolapse can be divided into the following stages due to the different duration of the disease. The blood that comes down is either a line like an arrow or a drop, no pain, no prolapse, and is characterized by blood. Middle stage: The hemorrhoid nucleus is larger, soft, bright red or greenish-purple on the surface of the hemorrhoid, the hemorrhoid nucleus prolapses out of the anus during the stool, and after the stool it comes back on its own, bleeding more or less after the stool. Later stage: The hemorrhoid nucleus is larger, harder, with a slightly grayish surface (i.e. fibrous internal hemorrhoid), and the nucleus comes out of the anus during stool, even when walking, coughing, sneezing, or standing, and cannot be retracted by itself. Complications: In the middle and late stages, there may be anal swelling and itching. If the hemorrhoid nucleus is acutely thrombosed, it can cause swelling, pain, erosion, necrosis, or even suppuration, and secondary anal leakage. Long-term blood in the stool can cause anemia. External hemorrhoids occur below the dentate line of the anal canal and are made by enlarged varicose veins or repeated inflammation of the external piles. The main symptoms of external hemorrhoids are swelling, pain, and foreign body sensation. It can be divided into superfluous external hemorrhoids, varicose external hemorrhoids and thrombotic external hemorrhoids according to their development process. Superfluous external hemorrhoids: Superfluous skin flap at the edge of the anus, gradually increasing in size, soft texture, generally no pain, no bleeding, only feel a foreign body feeling in the anus, occasionally swollen and congested with poison, only feel pain, once the swelling disappears, superfluous skin still exists. Venous exenteration external hemorrhoids: Mostly due to repeated prolapse of internal hemorrhoids in the middle and late stages, or due to increased abdominal pressure during maternal pregnancy, resulting in obstruction of superficial venous and subcutaneous lymphatic reflux, causing enlargement and varicosity of the external venous plexus below the dentate line of the anal canal. Its clinical manifestation: local oval or long swelling, soft to touch, usually not obvious, when defecating or squatting to increase abdominal pressure, the volume of the swelling increases dark purple, hard to press, after defecation or after massage, the volume of the swelling can be reduced to soft. If the swelling does not shrink after defecation and causes edema in the surrounding tissues, there will be pain. Patients with varicose external hemorrhoids are often accompanied by internal hemorrhoids. Thrombosed external hemorrhoids: The thrombus is formed when the veins outside the hemorrhoid rupture and the blood coagulates quickly due to constipation and excessive force during defecation, or after strenuous exercise. Its clinical manifestation: sudden and severe pain in the anus and the appearance of a swelling, which is very sensitive and causes pain when touched, so the pain can be aggravated when defecating, sitting, walking, or even coughing. 3.Mixed hemorrhoids It is a mixed hemorrhoid when the varicose veins of internal and external hemorrhoids communicate and anastomose with each other, and the groove between the sphincter disappears, so that the internal and external hemorrhoids form a whole. It has the common characteristics of internal and external hemorrhoids.
