External hemorrhoid surgery is still relatively painful because external hemorrhoids are located below the dentate line of the anal canal rectum, and this area is mainly innervated by the somatic nerves and is more sensitive to pain, especially if the patient himself is more sensitive to pain, which may be more intense in this case. It is generally recommended that for external hemorrhoid surgery, you can choose lidocaine or procaine for local infiltration anesthesia, which can relieve the pain from the surgery to some extent. You can also choose general anesthesia or lumbar anesthesia directly, so that the patient feels no pain during the procedure. However, after hemorrhoid surgery, because of the need for frequent bowel movements, feces can easily irritate the wound and thus cause pain, and there may also be an inflammatory infection in the wound, which can lead to severe pain. For this situation, you can choose diclofenac sodium suppositories to be inserted into the anus during the medication change process to provide an anti-inflammatory and analgesic effect, pay attention to the dryness and hygiene of the perianal area, and insist on medication changes to promote wound healing as soon as possible.
