In chronic migraine, Botulinum toxin has been studied to work by inhibiting the nerves that cause pain. Therefore, it is a preventative treatment to reduce the onset of a migraine.
Typically patients report that having Botulinum toxin injections for their headaches reduces having pain from 3 out of 4 weeks down to 1 in 4 weeks. This means your quality of life will improve and your wipe out days should decrease.
Neurology consult will be sought prior to Botulinum injections.
