Around 500,000 Irish people suffer from long-term physical pain, according to an EU-wide research project.
The study said a quarter of all Irish households are affected by chronic pain, with one-in-six sufferers losing their jobs because of the condition.
It also said that around 20% of chronic pain sufferers in Ireland contemplated committing suicide.
Responding to the research, the Irish Pain Society said long-term pain was a major public health issue and should be dealt with accordingly.
