UN to make pain relief a priority
In the UK if you get sick, or are in pain, doctors can give you strong medicine to help.
But in many poorer countries, those types of painkillers aren't available and people are having to live without access to pain relief.
Doctors say, in 2012, almost 18 million children, and adults, faced unnecessary pain when they got very ill.
Last month, health officials from almost 200 countries met and promised to make pain relief a top priority.
According to an organisation called The Worldwide Palliative Care Alliance, many governments across the world refuse to give patients access to strong painkillers because of worries they will become addicted to them.
