Can you tell me how long does an external hemorrhoid take to heal?

Hard to say: What some people call an external hemorrhoid is actually a skin tag. When a hemorrhoid (vein in the rectum) becomes distended, it can distend external skin. This sometimes shrinks back down, but sometimes leaves redundant skin that remains. If the external swelling is recent, it should shrink down as much as it is going to within 2-3 months at the most.
