A new study from researchers at the UK's University College London (UCL) has examined a rare condition that makes people unable to feel pain, known as congenital insensitivity to pain (CIP).

It's important to know how much pain young hospital patients are

As it stands, there's not a whole lot we know about pain. Where a tissue or blood sample can be drawn and studied, our nervous system comprising different kinds of cells running signals through complex piping around the body presents a difficult task for scientific research.

By extension, it is hoped that it could lead to new forms of pain relief that do away with unwanted side effects such as sleepiness or loss of concentration.
