What can be the cause of a headache in the same location behind my eye almost everyday? i can feel my heartbeat in my head.

Tension/migraine/eye: A daily headache is a litle different than things like migraines (although they can be frequent and do throb). A condition called chronic daily headache exists that is tough to manage. Headaches can have many causes including drugs, caffeine, otc med use, inflammation, migraines, tension and so on. To diagnose it needs more symptoms and some exam. Problems in the eye can also cause headaches.

Migraine: This sounds much like a migraine headache. No persistent headache should be taken lightly. See your family md this week and have a thorough evaluation. Continuing headaches need evaluation.

Should be evaluated: The described symptoms are not often indicative of a significant brain problem. However, abnormal clusters of blood vessels in the brain or its coverings can cause the above symptoms and often require treatment. The medical term for these conditions is avm (arteriovenous malformation) or dural malformation.
