Hemorrhoid injection therapy takes about 20 days to heal. Injectable therapy is generally suitable for milder hemorrhoids, i.e. first or second degree internal hemorrhoids, but if the patient has heavy hemorrhoids, such as third or fourth degree internal hemorrhoids, injectable therapy is not suitable. The cause of hemorrhoids is caused by the subluxation of the anal cushion or varicose veins, which usually manifests as a protruding swelling in the anus or bleeding in the anus after defecation, and most of the bleeding is caused by the breakdown of the varicose veins. The treatment can be done by injecting sclerosing agent on the surface of the varicose vein, i.e. submucosa, but the sclerosing agent must not be injected into the varicose vein mass, otherwise it may aggravate the hemorrhoid or cause bleeding. After the injection, usually 5-6 days need to re-examine, if the patient’s hemorrhoid nucleus does not significantly recede, you can also inject again, usually a hemorrhoid nucleus need to be injected 2-3 times, usually can be good, the total time required about 20 days.
