    What are the symptoms of Hemorrhoids ?
    ### Response:
    The most common symptom of internal hemorrhoids is bright red blood on stool, on toilet paper, or in the toilet bowl after a bowel movement. Internal hemorrhoids that are not prolapsed are usually not painful. Prolapsed hemorrhoids often cause pain, discomfort, and anal itching.
