ACCORDING TO LOCATION – WHERE DOES IT HURT?
Pain is often classified according to its location on the body. Two overlapping schemes relate the pain to the specific anatomy and/or body system thought to be involved. The anatomic pain classification system identifies sites of pain as viewed from a regional perspective (e.g. lower back pain, headache, pelvic pain). In contrast, the body system pain classification method focuses on classical body systems (e.g. musculoskeletal, neurological, vascular). Yet, both classification systems address only a single dimension (i.e. where or why does the patient hurt) and thus may ultimately fail to adequately define the underlying neurophysiology of the problem.1
