Has anyone experienced migraines after ACDF ? I'm almost 3 months post op and as soon as I was told to start taking off the brace at 2 weeks post op extreme headache and migranes began. My migraine is triggered by a weather changes, especially thunderstorms . Neurologist says my migrane is caused by neck muscle spasms. Half of my chin has numbness sensation and I was told by two physical therapists that it is a side affect left from the surgery and it will not return back to normal. Is anyone else experiencing the same issues?
