Hemorrhoids are swollen blood vessels on the outer rectum and anus. They can turn bowel movements into intensely painful experiences. Classic symptoms include rectal pain, itching, bleeding, and possibly prolapse (protrusion of hemorrhoids into the anal canal). Although hemorrhoids are rarely dangerous, they can be a painful recurrent bother. Simple self-help measures can ease the ordeal of most hemorrhoids and allow healing. These include: Step up the fiber. Lubricate the process. Don’t delay having bowel movements. Try over-the-counter remedies. And sit in a sitz.
