what does a hemorrhoids look like,Original Why are some hemorrhoids painful? Some hemorrhoids are not painful? What kind of hemorrhoids need surgical treatment?

    Painless hemorrhoids are mainly internal hemorrhoids, because internal hemorrhoids are located on the dental line (the dividing line between the anal canal and rectum) and are innervated by visceral nerves. The visceral nerves are not sensitive to pain. Therefore, although internal hemorrhoids have symptoms such as bleeding, they do not feel pain. . Hemorrhoids that cause pain are mainly external hemorrhoids, mixed hemorrhoids and internal hemorrhoids incarcerated, especially thrombotic external hemorrhoids and inflammatory external hemorrhoids. The pain is the most obvious. This is because the external hemorrhoids are located below the dental line and are innervated by the spinal nerve. This nerve is the pain nerve, so after the illness Sensitive to pain. When internal hemorrhoids are incarcerated, the anal margin swells, thrombosis, and the pain is also very obvious.

    A foreign scholar said: "Don't treat symptoms without anal signs, and don't treat anal signs without symptoms." Anal signs refer to changes in hemorrhoids found in local examination of the anus. Symptoms include blood in the stool, prolapse, anal dampness, anal itching, and anal pain. The meaning of this passage is that only when the symptoms and anal signs are present at the same time can there be surgical treatment significance.

    It is generally believed that hemorrhoids have only local signs and do not require immediate surgical treatment, but as soon as possible surgical treatment of hemorrhoids is very beneficial when clinical symptoms appear. If hemorrhoids are bleeding, long-term failure will lead to pernicious anemia and cause serious damage to the body; if hemorrhoids prolapse, if they are not treated in time, hemorrhoids may be prolapsed and incarcerated and necrotic, which is not only painful, but also causes hemorrhage and sequelae after surgery. .
