So, your neurologist: & neurosurgeon have done serial neurological exams, MRI's of your brain & neck, & other tests over the past year that show no increased intracranial pressure, Chiari malformation or shunt malfunction? Then see your dentist & your primary care doctor to rule out referred dental/TMJ pain, chronic sinusitis, high blood pressure, anemia, other systemic illness or possible vision problems.

See neurosurgeon: See your neurosurgeon. If your shunt is working then a neurologist to diagnose the cause of your headachess
