Bleeding hemorrhoids do not cause fever. Hemorrhoids are perianal blood vessels stasis and abnormal tortuous, dilated, clinical manifestations of post-poo anal drip, blood on the surface of the stool, can be accompanied by anal itching, cramping discomfort, will not be accompanied by fever. When the hemorrhoid becomes embedded and forms a thrombosed external hemorrhoid, the anal sphincter muscle contracts violently, which can aggravate the stasis of the hemorrhoidal vein and cause necrosis and detachment of the hemorrhoid nucleus, and low fever with pain can occur. When you have a fever and the hemorrhoid does not form a thrombosed external hemorrhoid and necrosis, you should go to a regular hospital for routine blood or chest CT examination to clarify the cause of the fever and actively give anti-infection treatment. In daily life, you should eat a light diet, avoid eating too much spicy, stimulating, raw and cold food, and keep your bowels open and your anus clean.
