Dr Paul Masterman
BSc(Hons) PhD(Clinical Psychology)
Paul is a clinical psychologist specialising in the management of persistent pain. He has over 20 years’ experience working in public hospitals, private practice and community settings.
Paul helps people who live with chronic pain to understand the role that central nervous system sensitivity can play in their experience of long-term pain. CNS sensitivity has strong associations with anxiety and mood and the distress that comes with chronic pain. This understanding of how we experience pain opens opportunities for a range of psychological strategies to create positive change, improve quality of life and to reduce pain.
