Understanding Allodynia in Chronic Migraine Patients Allodynia refers to a condition in which pain is experienced in response to non-painful stimuli, such as brushing one's hair, wearing glasses, or even feeling a light breeze. It frequently forms in someone with frequent migraines because of the repetitive stimulation of the pain system in the brain. In terms of migraine, allodynia is an indicator of central sensitization in which the nervous system becomes hypersensitive to various stimuli. The moment it is not taken care of, it can make the migraines more incapacitating and difficult to cure. Management is usually the prevention of the increase of migraine and decreasing sensitization. This comprises prevention (via migraine-specific treatment, lifestyle changes, and occasionally prophylactic drugs under expert supervision).
