Hello. I have chronic daily headaches lately- especially in the last few months. I have a Vp shunt due to severe hydrocephalus. I have had my shunt for 3 years. I have had my setting changed 15+ times and an anti-siphon device placed. MRIs show that my ventricles look normal. I've tried everything. I'm on anti-seizure meds (since having surgery I developed epilepsy.) does anyone out there with a vp have terrible headaches that come and go like this?
