Most external hemorrhoid surgeries are more painful than internal hemorrhoid surgeries, mainly because the external hemorrhoid surgery area is innervated by the internal pubic nerve, which is sensitive to pain. External hemorrhoids are mainly located below the dentate line, and this area is mainly skin tissue that is innervated by the internal pubic nerve, the trunk nerve, which is sensitive to pain. Therefore, when surgically treated the pain is more intense due to the irritation of the wound. Internal hemorrhoids are mainly located above the dentate line and are innervated by autonomic nerves, and visceral nerves, which are sensitive to pulling and insensitive to pain. Therefore, internal hemorrhoids and internal hemorrhoid surgery postoperative pain is not as sensitive as external hemorrhoids. For pain-sensitive external hemorrhoids after surgery, pain medication is usually given, such as intramuscular injection of parecoxib sodium, or oral pain medication acetaminophen, tramadol hydrochloride extended-release tablets. These medications should be used under the direction of a physician. It is recommended that hemorrhoid patients actively follow the doctor’s instructions after surgery, which is conducive to the recovery of the disease and achieve the prognosis.
