This study forms part of a longitudinal investigation of pain, disability and health care use in primary care low back pain consulters. Sixteen purposively sampled patients and their health care professionals were interviewed about experiences with back pain and their therapeutic relationships. This case study draws on the accounts of one patient, his wife, and three health care professionals and explores the role of the informal carer in back pain care. The interview with the patient and his wife highlights the dynamics of a co-constructed narrative of back pain.
