Note: A medical study mentions that “These injuries are rare. Its prevalence is difficult to define due to the large number of etiological mechanisms (multiple types of traumatic agents, injuries, among others)”. (two)


Hemorrhoids are common and natural in the human body , they are blood vessels (veins) in the rectal area, shaped like padstag. Despite this, they can become dilated or inflamed and be very annoying. When these blood vessels break, they createlimiting anal bleeding.
