Chronic (Persistent) Post-Surgical Pain – What can I do?

Chronic (Persistent) Post-Surgical Pain – What can I do?


Definitions of pain vary widely, and post-surgical pain is no different. 2017 was the Global Year Against Pain After Surgery as declared by the IASP (International Association for the Study of Pain).

A working definition of chronic post-surgical pain (CPSP) is pain that:

  • persists for at least 3 months after surgery,

  • was not present before surgery and/or different characteristics or increased intensity from pre-operative pain,

  • occurs in surgical site and/or referred area, and

  • is not due to other causes, e.g. infection, disease recurrence, or surgical complication [2].
