Ice Pick Headaches
“Ouch!” you scream as a searing bolt of pain hits your head. Before you can explain what just happened, the pain is gone. It only lasted seconds, but felt like you’d just been stabbed in the head with an ice pick.
They’re called primary stabbing headaches, or more commonly, “ice pick headaches.” While not migraine attacks, they do occur in patients with a history of migraine. In most cases they are infrequent and require no special treatment. However, patients who experience frequent attacks may be prescribed Indomethacin as a preventive. Indomethacin is a prescription NSAID with a high rate of gastrointestinal side effects. Many times doctors will prescribe a proton-pump inhibitor (like Prilosec) to be taken along with indomethacin as a precaution.
Diagnosing primary stabbing headache
Primary stabbing headaches most often affect the same side as migraine attacks. Most of the time the stabbing is felt in the occipital and temporal regions rather than in the face or eye, so it generally does not involve the trigeminal nerve. The pain can vary from one location to another. If attacks occur in exactly the same spot over and over, your doctor may want to rule out structural or functional changes that better explain your symptoms.
What sets this headache disorder apart from others that involve stabbing pain is the irregular occurrence and lack of redness or tearing of the eyes. If the attacks occur in a predictable pattern or include eye redness and tearing, then a visit to your headache specialist is warranted to rule out more serious headache disorders such as cluster headache, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), short lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA), or trigeminal neuralgia.
