An abnormal or uncomfortable sensation in response to a stimulus that normally produces mild sensation; altered sensation such as tingling, burning, or numbness.
From Greek dys- (bad, abnormal) + aisthesis (sensation, perception). This neurological term describes when the nervous system misinterprets normal sensations, making them feel wrong or unpleasant rather than painful.
Dysesthesia explains the 'pins and needles' feeling when your foot falls asleep, or the weird burning neuropathy diabetics experience—your nerves are reporting correctly, just badly. It's technically not pain, but something equally troubling.
