I have a stabbing pain in the back left side of my skull. I can even put my finger on the spot that has been hurting. It hurts off and on all day, and it causes a pain in my left ear, as if my ear needs to pop but won't. Is this an icepick headache?
Nobody can diagnose via the Internet, so even with more information, I couldn't say whether you're having an ice pick headache.
Ice pick headaches generally last between five and 30 seconds, but can occur several times in a day. For more information about ice pick headaches, please see Ice Pick Headaches - The Basics.
Unexplained head pain should always be investigated. Please see your doctor or go to an urgent care facility or ER.
