Are hemorrhoids painful?

Maybe: External hemorrhoids usually hurt and occassionally bleed, internal hemorrhoids usually bleed without pain unless they prolapse to the outside. Prolapsed internal hemorrhoids are not external hemorrhoids and are treated differently than true external hemorrhoids. Bleeding and pain is often a fissure. Get a colon and rectal surgeon to evaluate it properly.

Yes laterstages : Group of blood vessels near anorectal area, where systemic and portal vessels meet.Will cause pain at later stages.
