While vacationing last week, I saw a blimp of a report on CBS about cluster headaches and there cause. Unfortunately, I missed all but the last few seconds. It stated that CH's are a physical problem and not a vascular issue. I have surfed the web and found nothing. Let me know if anyone out there saw this report, or knows of this finding. Thanks
