Investigations
Icepick headache itself is a benign condition and needs no tests. If you have never had a headache like this before however, you should consult your doctor, as other serious conditions causing headache need to be excluded.
Treatment
The headaches themselves are too short for treatment to be useful. If the patient is having frequent, disabling headaches, then a tablet to prevent the attacks may be tried. The medication most frequently used is Indomethacin .
