The hemorrhoid injection treatment is sclerotherapy for hemorrhoids, which is suitable for relatively mild hemorrhoids, such as first or second degree internal hemorrhoids, and if the patient’s hemorrhoid symptoms are more severe, surgical treatment should be used to do so. The sclerosing agent is usually 5% carbolic acid, which is injected on the surface of the rectal vein mass inside the anus, not inside the vein, and when injected under the mucosa, the change in the color of the mucosa should be observed, and if the color of the mucosa turns white, the drug injection should be stopped immediately, and the patient’s bowel movements should be observed after the injection treatment, whether there is bleeding, etc. If the treatment can also be re-injected after 5-6 days, the patient’s hemorrhoids can generally subside after 2-3 courses of regular injections, and the pain can be relieved.
