I am now the boss of my pain - it no longer controls me

For years Julie-Ann Walkden had relied on pills and injections to cope with chronic pain, but it was an understanding of what was going on that helped her get her life back.

"I didn't want to take strong medication which made me feel ill, not in control and often so confused that I felt I'd dementia," she said.

She was among more than 100 patients who have completed a pain rehabilitation programme, using exercise, talking and psychological therapies to help them understand the source of their pain.

Walkden was speaking after a new study revealed that people in the most deprived socio-economic areas of Northern Ireland are at higher risk of chronic pain and three times more likely to face pain-related depression.

Ten years ago, Walkden, 58, was prescribed strong pain medication for a long-standing stomach injury, but said it only provided short-term relief and made her feel worse.

However, she found new ways of coping with her condition following a three-week intensive programme at Knockbracken Health Care Park in Belfast, which teaches psychological techniques to deal with pain rather than relying on medication.

"The tools have allowed me to become the boss of the pain instead of it controlling me," she said.

"I am not afraid to exercise, especially to walk, I even talk to the pain but I no longer allow it to prevent me from living a life.

"Understanding the source of my pain and what it is doing to me mentally, never mind physically, has been life changing."

Data collected from the Knockbracken programme has formed part of new research from Queen's University Belfast (QUB) and the Belfast Health Trust.

While more than 100 people within the Belfast Trust physically took part, the study also analysed the data of 491 patients living with chronic pain in Northern Ireland.

It found that 42% of those were living in the most deprived areas and reported much higher levels of distress, disability and pain-related burden.

Professor Kevin Vowles from QUB, who led the study, said: "What we found is that individuals who live in high areas of social deprivation are at substantially increased risk of huge disruptions in social functioning, emotional functioning, physical functioning.

"The degree of that difference is so significant that as researchers and clinicians we were genuinely shocked; we did not expect the result to be as bad as it was.
