'My life is controlled by the pain'
The number of painkilling prescriptions being issued to patients in Wales has risen 20% in the past five years.
Experts say thousands of patients are receiving painkillers because specialist services to help them cope with chronic pain are underfunded.
Painkillers cost the Welsh NHS almost £50m last year.
In Wales, 30% of people are in pain and one in eight people suffer chronic non-malignant pain.
The BBC Wales current affairs series Week In Week Out spoke to four people - Bob Rees, Carol Ross, Julie-Anne Grey and Sian Finselbach - about their own experiences of pain.
