Can internal hemmorhoids heal? Had bleeding but dr said there were no internal hemmorhoids. Haven't had any blood with bowel movement for 2.5 years now

Born with them. It may be that whatever caused your bleeding 2 1/2 years ago wasn't internal hemorrhoids or that you made good changes to lifestyle, diet or bowel behaviors at that time so that you no longer have hemorrhoidal bleeding. They don't need to go away to heal. Remember everyone is born with hemorrhoids, they just don't give us symptoms unless we don't take care. Good luck!
