Internal hemorrhoids originate in the inner part of the lower rectum. This type of hemorrhoids lacks nerve cells. This is why internal hemorrhoids are painless.
External hemorrhoids develop below the rectal opening or surrounding the anus. They are situated under the skin, and the presence of nerve cells make these hemorrhoids very painful.
Most hemorrhoids are internal but both types of hemorrhoids can be present at the same time in the same person.

Internal hemorrhoids are painless with light red rectal bleeding with stools, itching, burning, mucus discharge or excessive moisture, visible bulge (prolapsed) mass, thrombosis (obstruction due to blood clot).
Prolapsed hemorrhoids are internal hemorrhoids that stick out through the anus when the stool is passed or when a person stands, and are usually painful. Thrombosed hemorrhoids appear as blue, shiny masses, and are very painful. Thrombosed external hemorrhoids could occur within the first day after delivery.
