Hemorrhoids can be treated with injections, which are suitable for internal hemorrhoids of the first or second degree, and patients with milder conditions can be treated with injections, which are sclerotherapy injections. Usually 5% carbolic acid is used to inject under the mucous membrane of the varicose veins of the hemorrhoids, not inside the veins. After the injection, you should observe the changes in the nucleus pulposus of the hemorrhoid and the situation of defecation, whether there is bleeding in the anus after defecation or the nucleus pulposus continues to be enlarged. If the recovery of the hemorrhoid nucleus is not very obvious, you can also inject again after a week, usually in about a month of treatment, the patient’s condition can be recovered.
