Shot in the dark: three patients successfully treated with onabotulinumtoxin A injections for relief of post-traumatic chronic headaches and dystonia induced by gunshot wounds.

Three patients ranging from 49 to 61 years-old presented to our pain clinic after failing multiple treatment attempts for debilitating, chronic post-traumatic headaches, neck pain and involuntary muscle spasm following gunshot wounds to the head, neck and face. Concurrent cervical dystonia was noted in each patient on presentation. All patients were treated with onabotulinumtoxin A (ONA) injections in the head and neck.
