Chronic wound pain

Lore & Background

Chronic wound pain is classified into nociceptive and neuropathic pain. Nociceptive pain is a physiological response to tissue damage, described as stabbing, throbbing, aching, or sharp, and may be acute or chronic. Neuropathic pain results from nervous system dysfunction, causing burning or tingling persistent pain. Three types of nociceptive pain occur with chronic wounds: cyclic acute wound pain (during routines like dressing changes), noncyclic acute wound pain (during procedures like debridement), and chronic wound pain (persistent at rest).

Reader's Guide

Chronic wound pain has been underrecognized and often goes untreated or undertreated due to inadequate assessment. The most valid indicator of pain is the individual's verbal report, and standardized tools such as the Visual Analogue Scale, Numeric Box Scale, Faces Pain Rating Scale, and Short McGill Pain Questionnaire are used for assessment. The Wound Pain Management Model outlines key components: location, intensity, duration, and impact on quality of life. Negative consequences include sleep deprivation, immobility, depression, changes in body image, constipation from pain medications, infection, and stress. Effective management requires determining the pain type, as neuropathic pain may need different interventions than traditional analgesics used for nociceptive pain.
