Anaesthesia · Pain physiology: neuropathic pain
Sample itemA 58-year-old diabetic describes burning pain in both feet with sudden electric-shock sensations. Light touch from bedsheets is painful, and there is a stocking pattern of sensory loss. What type of pain is this?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Neuropathic pain
Neuropathic pain arises from a lesion or disease of the somatosensory nervous system and is described as burning or shooting, with allodynia and sensory deficit. First-line drugs include gabapentinoids, tricyclic antidepressants and duloxetine, while simple analgesics work poorly.
Option by option
A. Referred pain
Referred pain is felt at a distant site that shares segmental supply with a diseased organ.
B. Somatic nociceptive pain
Somatic nociceptive pain is a well-localised aching from skin, bone or muscle injury, without allodynia and deficit.
C. Neuropathic pain (correct)
Correct. Burning, shooting pain with allodynia and sensory loss indicates nerve damage.
D. Visceral pain
Visceral pain is a poorly localised, deep, cramping pain from internal organs.
