Allodynia – Allodynia is a symptom of central sensitization or nerve damage where non-painful stimuli—such as light touch, brushing hair, or mild temperature changes—cause pain. Often linked to conditions like migraines, fibromyalgia, or postherpetic neuralgia, it typically results from altered pain processing in the nervous system. Treatment focuses on managing underlying conditions and using specialized nerve pain medications.
