Hemorrhoid injection therapy takes about 20 days to heal. Injection therapy is generally applicable to relatively mild hemorrhoids, that is, one degree or two degrees of internal hemorrhoids, if the patient hemorrhoids are more heavy, such as three degrees or four degrees of internal hemorrhoids, with injection therapy is not very suitable. The cause of hemorrhoids is due to the downward movement of the anal cushion or the varicose vein mass, which is usually manifested by a swelling protruding from the anus or bleeding from the anus after defecation, and most of the bleeding is caused by the varicose veins breaking down. Sclerosing agent can be injected on the surface of the varicose vein, that is, submucosal injection to carry on the treatment, must not inject the sclerosing agent into the inside of the varicose vein mass, otherwise it may aggravate the hemorrhoids or cause bleeding and so on. After the injection, usually 5-6 days need to be re-examined, if the patient’s hemorrhoidal nucleus does not obviously subside, can also be injected again, usually a hemorrhoidal nucleus needs to be injected 2-3 times, usually can be good, a total of time will take about 20 days.
