What is the cause of these reccuring headaches?

CHRONIC HEADACHE: Recurrent episodic headache can be migraine, migraine headache is episodic, frontal , throbbing, associated with nausea, vomiting, light and noise intolerance. If your headache is coming more than once a week, you need to see your doctor to start you on a preventive medication.

Cervicogenic: Not all headaches are migraines. A really bad headache is not a migraine. The large majority of all headaches come from the neck. The pain travels into the head region and then can trigger, if left untreated, migraine-like symptoms called "secondary migraines", with the same symptoms as regular migraines. If standard treatments aren't working to control ha, look into neck.

Get checked out: A good start at finding potential headache triggers would be to maintain a diary. Every time you have a headache write down what you were doing, the foods you ate that day, alcohol, smoking, caffeine, stress, how much sleep you had the night before, eye strain, etc. Try to find patterns in your headache so that you can learn what things to avoid. Get checked by your doctor.
