The boy who feels no pain

Isaac Brown is a 5-year-old boy from Iowa who suffers from a rare genetic condition which makes him immune to pain, but not to the effects of his frequent injuries.
Isaac was born with a congenital insensitivity to pain (CIP) and, according to his parents, the first years of his life years were especially hard as the boy “would just drop to the ground and smack his face on the table. He thought the fall was fun.
His parents sought medical help but were disappointed to find that his condition was untreatable. The only advice medics were able to give the couple was to teach Isaac to recognize pain.
