What causes a stabbing pain in the left temple?

A stabbing pain at the left temple may indicate a 'primary stabbing headache,' commonly referred to as an 'ice pick headache,' according to HealthCentral. Such headaches occur in isolated areas of the head, generally lasting just a few seconds at a time.

The stabbing pain caused by ice pick headaches is most often experienced near the temple or parietal region of the head, says HealthCentral. The headaches are more likely to occur in individuals who suffer from other primary headache disorders, such as migraines. Ice pick headaches are categorized as primary headaches because they are not rooted to an underlying condition or defect.
