Stool pain on the 9th day of hemorrhoid surgery is a common phenomenon because most hemorrhoid surgery incisions are usually open, and local irritation, downward displacement of the anal cushion, and wound infection may produce pain, which can be improved by dietary adjustments or the use of medications. As most of the incisions for hemorrhoid surgery are open, and open incisions are susceptible to local irritation and pain. Pain occurs when the patient irritates the hemorrhoidal incision by straining too hard or by drying the stool during bowel movements. In addition, if the anal cushion moves downward during defecation, it may pull on the incision and cause local pain symptoms. Meanwhile, surgical incisions, localized superficial infections or friction can likewise irritate the sphincter muscles around the anus, leading to spasm and pain. Hemorrhoid surgery patients should increase water intake appropriately, eat more food rich in dietary fiber that helps bowel movements, and try to eat liquid food to avoid constipation and dry stools. In case of constipation or difficulty in defecation, you can also use corkscrew under doctor’s instruction to assist defecation and relieve pain. In summary, hemorrhoid surgery on the 9th day of stool pain is generally a normal phenomenon, if the patient appears serious or persistent pain, should go to the hospital in a timely manner, so as not to delay the condition.
