I have a headache all the time, what causes this?

Maybe migraine: Frequent ha's can be migraines, tension events, but can be due to neck problems, issues within the cranium, and even associated with chronic infections. Some medicines or even b vitamins may cause headaches as side effects.

Anything: Headaches can come from fatigue, sleeping too much or too little, eye strain, sleep apnea, snoring, being dehydrated, having chronic sinusitis or allergies, too much caffeine or over the counter headache medication, high blood pressure or something more serious like a tumor. See your doctor and get checked.
