Hello, Thanks for the query, I understand your concern Let me tell you that headache can be due to many causes and it can be due to migraine, tension headache, brain tumor/infection/bleed etc. I will request you to get evaluated by a neurologist who will examine you and help you through evaluation including a brain scan if needed. I feel that you have migraine headache and you will improve with anti-migraine medications. Medications that will help you are amitriptiline, topiramate, valproate, propranolol etc for chronic use and for acute attack, medications that will help are analgesics like ibuprofen, indomethacin etc. You need to have a regular food and sleep habit too. Temporal arteritis is basically a disaese of old age and will generally will occur in this age. If you are concerned, you can do a simple blood test, called ESR- Erythrocyte sedimentation rate , which will be very high in temporal arteritis. You may not go to the ER. You can meet a local neurologist in his office.
