Explanation: 

Detailed explanation-1: -Young children with congenital insensitivity to pain may have mouth or finger wounds due to repeated self-biting and may also experience multiple burn-related injuries. These repeated injuries often lead to a reduced life expectancy in people with congenital insensitivity to pain.

Detailed explanation-2: -Congenital insensitivity to pain and anhydrosis (CIPA) is a very rare and extremely dangerous condition. People with CIPA cannot feel pain [1]. Pain-sensing nerves in these patients are not properly connected in parts of brain that receive the pain messages.

Detailed explanation-3: -Adrenaline masks pain The body has a way of tricking us into feeling like we’re not hurt. It releases adrenaline when a crash or other traumatic accident occurs, according to CNN. The stress we feel in these situations could mask the pain of an injury for several hours, even days.

Detailed explanation-4: -Most people afflicted with the disorder do not live past age 3, though not all deaths are due to the lack of pain. In fact, half of CIPA deaths are due to overheating because of the person’s inability to produce sweat. This causes hyperthermia, or extremely elevated body temperature, which then leads to death.

Detailed explanation-5: -Jo Cameron only realises her skin is burning when she smells singed flesh. She often burns her arms on the oven, but feels no pain to warn her. That’s because she is one of only two people in the world known to have a rare genetic mutation. It means she feels virtually no pain, and never feels anxious or afraid.
