How long has this been going on? How often does it happen?
Are you there?
Twice this year enough to make me stop driving only lasts for less than one minute or so
does it involve the eye at all...pain, watering, blurred vision?
This could represent one of the trigeminal autonomic cephalgias. The trigeminal nerve is the 5th cranial nerve (there is one on each side of the head). It supplies sensation to the temple region as well as the face. It can be easily irritated and can cause severe boring or lancinating pain.
Short lasting unilateral neuralgiform (SUNCT) headache attacks are very brief, lasting between 5–250 seconds (mean duration 49 seconds). The paroxysms begin abruptly, reaching the maximum intensity within 2–3 seconds; the pain is maintained at the maximum intensity before abating rapidly. Most patients are completely pain-free between attacks.
If these attacks increase in frequency, you can try treating them with indomethacin. This is an anti-inflammatory that often helps.
If ineffective, you could try carbamazepine or lamotrigine. These are typically effective at preventing the attacks.
Please let me know if you have any follow up questions about this.
