Botulinum toxin as treatment of chronic migraine

Chronic migraine is a severely disabling neurological condition characterized by episodes of pulsating unilateral or bilateral headache. The Food and Drug Administration (FDA) approved in 2010 injections of botulinum toxin as treatment of chronic migraines. It is effective in the reduction of headache frequency and severity in patients. It can be injected by licensed medical professionals into multiple areas around the head and neck.
