Nociceptive Pain
Pain caused by on-going activation of pain fibres by a noxious
stimulus. Two sub-types:
a) Somatic Pain (e.g. bone metastases, muscle or soft tissue
damage). This is described as pain that is well-localized,
gnawing, dull, boring, aching or occasionally cramping. It
may be constant or intermittent. Pressing over the affected
area elicits pain or makes it worse. It is also usually worse
with movement.
b) Visceral Pain (e.g. liver metastases, GI infection). This is
described as a constant deep aching, squeezing or cramping
pain that is usually poorly localized or diffuse. It can be
referred (e.g. to sacral or perineal area). It is often associated
with autonomic symptoms including sweating and pallor
