Had headache, earache and watering eyefor 6 months had sinsus ct came back normal. ent says headache is migraine and prescribed beta blocker. correct?

Dry eye?: Migraines do not typically cause tearing. However, pain from dry eyes is poorly localized and so dry eyes could potentially cause all 3 symptoms. Try otc artificial tears as a trial.

Check jaws: Migraine does not usually affect the ears and thus you may have another kind of headache altogether or in addition to migraine. Beta blocker is often used for migraine prophylaxis but if you have more than 15 episodes a month, Botox may be another option. Do consult your dentist to find out if you have a jaw problem called tmd.

Perhaps is migraine: Worthwhile to try a preventative medication, and beta blockers are approved for migraine, but, they may have nasty side effects such as wheezing, fatigue, cognitive slowing, exercise intolerance, slowing of pulse and dropping of blood pressure, and depression. Other meds may be tolerated better such as topirimate or divalproex sodium. Perhaps, see a neurologist who focuses in headache management.
