Hemorrhoids are a common condition that can cause discomfort and bleeding. Although they often resolve on their own, persistent hemorrhoids may require medical treatment. You should see a doctor if you experience any of the following: rectal bleeding, prolapse (where the hemorrhoid protrudes through the anus), pain or discomfort during bowel movements, itching or irritation in the anal area, or a sensation of fullness in the rectum. If you have any concerns about your hemorrhoids, it is important to speak to a doctor so that they can rule out any other potential causes of your symptoms.
