Topical Lidocaine Appears Promising as Treatment for Migraine
This is an interesting article because of its implications. A few things to consider. Migraines are believed to be related to some sort of electrical disturbance within the brain itself. If this is the case, then why would a topical anesthetic have an effect on these migraines? The author suggests that the lidocaine may affect the trigeminal ganglion, the housing for the cell bodies of the neurons going to many areas of the face. Could it be that many migraines are misdiagnosed, and the vast majority of them are truly tension-type headaches? There is still so much we do not understand about the human nervous system.
