Hello ! I understand your concern. In my opinion this may be a headache type called Primary stabbing Headache , also called Ice peak headache. It is more common in persons suffering from Migraine. A trigeminal neuralgia should also be excluded. There is nothing you should worry about. This type of headache doesn t have any serious underlying cause. I would recommend treatment with Indomethacine suppository twice daily for some days . It is helpful in preventing the attacks. If the problem persists a brain MRI would be helpful to rule out any possible cause. Hope to have been helpful! Thank you for using HCM! Best wishes, Dr. Abaz
