Welcome to my Masterclass – ‘Pain – a guide for clinicians’. In this class I will guide you through the interview, reasoning and planning of therapy for patients suffering from pain. Although the focus is on chronic primary pain, the principles may equally be applied to all other pain conditions. The Masterclass covers topics ranging from the meaning of pain, what you must know about pain, and assessment of complex pain. It will ultimately leave you better equipped to assess and treat patients with painful conditions.
