Migraines are driven by more than triggers like stress, weather changes, or certain foods. At their core, chronic migraines involve changes in how the nervous system processes pain. Two key mechanisms: Peripheral Sensitization and Central Sensitization play a major role.
Peripheral sensitization occurs when pain-sensing nerves in the head, face, jaw, and neck become overly responsive. Repeated migraine attacks cause these nerves to fire more easily, meaning normal sensations such as light pressure or muscle tension can trigger significant pain.
Central sensitization develops over time as the brain and brainstem receive repeated pain signals. The nervous system becomes conditioned to amplify pain, lowering the threshold for migraine attacks. This explains why chronic migraines often become more frequent, more intense, and harder to control.
Botox (onabotulinumtoxinA) helps address both processes. At the peripheral level, it reduces the release of pain-mediating neurotransmitters, calming overactive nerve endings and reducing trigeminal nerve activation. This decreases the volume of pain signals sent to the brain.
By limiting ongoing peripheral input, Botox also helps reverse central sensitization. With fewer pain signals entering the nervous system, the brain gradually becomes less reactive. Over multiple treatment cycles, patients often experience fewer migraine days, reduced intensity, and improved tolerance to
triggers.
Understanding sensitization highlights why chronic migraines require preventive treatment rather than relying solely on acute medications. Addressing the underlying neurological drivers allows for more durable, long-term relief.
