What does an internal hemorroid feel like?

Depends: When early/small, they stay inside and can't be felt by u. When they get big enough, they will come out with bowel movement and in the most severe case, can't be pushed back in. They are usually purplish in color and one may feel soft mass. They can bleed and cause pain.

Can't feel: Grade 1 and 2hemorrhoids are internal. They cannot be felt externally. Symptoms are bleeding and occasionally a sense of fullness or constipation. Grade 3 hemorrhoids prolapse to the outside but go back in spontaneously. They can be felt while they are external. Grade 4 hemorrhoids prolapse externally and remain there. Hemorrhoids are painful when thrombosed or associated with anal fissure.
