Botox Injections for Chronic Migraines
Botox is licensed for the treatment of chronic migraine, defined as 3 months of at least 15 days of headaches a month, of which at least 8 days have migraine features, such as nausea, light or noise sensitivity, pulsating or lateralized pain.
How Does Botox for Chronic Migraines Work?
Botox or botulinum toxin, gets into the small nerves that carry pain from the head to the brain, known as C-fibres. Injections may reduce the amount of chemicals released from the nerve ending and therefore interrupts the feedback pathway that perpetuates migraines.
