See your Dr: Stabbing headaches, or “ice pick headaches,” are short, stabbing, extremely intense headaches that generally last only seconds or minutes, typically in a specific side/area of the head. People with new or never-evaluated stabbing headache should be carefully evaluated by a Dr for underlying causes. The Dr may manage the condition with Melatonin or Indomethacin prescription meds.
