In general, patients can distinguish internal hemorrhoids from external hemorrhoids by the location of occurrence, pain, bleeding conditions, etc. 1. Location: internal hemorrhoids are mainly located in the rectal terminal dentate line, and will form a pathologically enlarged soft mass above the rectal terminal dentate line. External hemorrhoids are located below the dentate line, mainly due to inflammation of the skin at the anal verge, connective tissue hyperplasia or varicose veins outside the hemorrhoids and other masses. 2. pain condition: because the internal hemorrhoid is located in the end of the rectum on the dentate line, above the dentate line is the rectum of the painless area, so generally does not produce pain. As external hemorrhoids are located below the dentate line, easy to cause inflammation and infection in the anal area, then there may be anal swelling and pain. 3. Bleeding condition: internal hemorrhoids in the early stage, then the symptoms of blood in the stool, followed by indirect dripping blood, ejaculation of blood and other symptoms. Then external hemorrhoids are usually bulging a bag under the skin, usually rarely bleeding symptoms. It should be noted that, if hemorrhoids once found and accompanied by uncomfortable symptoms, it is recommended that you should go to the hospital in time for relevant examinations, and give treatment as soon as possible.
