Full Answer

Internal hemorrhoids are often painless, according to Mayo Clinic. This is because there are few nerves that sense pain deep inside the rectum, claims WebMD. If a person strains when attempting to pass stool, the hemorrhoid can bleed or protrude into the anus. When this happens, it is a prolapsed hemorrhoid. The individual can sometimes push these hemorrhoids back into the rectum. Sometimes they return on their own.

Prolapsed internal hemorrhoids bleed, itch and cause pain, says Mayo Clinic. Since rectal bleeding can be a sign of a serious disease, such as colorectal cancer, an individual should consult a doctor regarding any instance of bleeding.

An internal hemorrhoid may swell if it is irritated, according to MedicineNet. This causes the muscles around the anus to spasm, which leads to pain. An irritated hemorrhoid also exudes mucus, which leads to anal itching and burning.

Hemorrhoids do not require treatment if they cause no symptoms, says MedicineNet. The risk of contracting hemorrhoids is lowered if the person drinks an adequate amount of water and adopts a diet that is high in fiber.
