Botulinum toxin is injected into seven muscles around the top of the forehead, above the ears and into the neck via a small needle. You will have around 31 small Botox injections. The areas can be numbed beforehand.
You may notice some redness and/or swelling around the injection points, which will settle after a few hours.
Repeated Botox injections for migraine treatment are needed every three months, usually until your chronic migraines change to episodic migraines for 12 weeks in a row.
