family history of stroke, parkinsons, cancer, is it migraine

Hi, and thanks for your medical question on eHealth forum!

Since you have a headache almost daily, what you have is in all probability not a simple migraine but a chronic daily headache (CDH). This can be the primary type—without any cause. One simple reason for daily headaches with nausea is compression of cervical spinal nerves. Another reason is TMJ, especially if the headache starts with chewing. The third reason could be severe acidity with or without GERD. The CDH could also be secondary to trauma, raised intracranial hypertension, high blood pressure, temporal arteritis etc. Hence all these need to be ruled out.

If the headache lasts for less than 4 hours then it could be a chronic cluster headache or a chronic paroxysmal hemicranias. Since a confirmed diagnosis cannot be given on net please discuss these possibilities with your doctor once. You may need some tests for confirmed diagnosis which may include blood tests, MRI etc. Hope this helps. Take care!
