I Need Some Help. I Have Idiopathic Intracranial Hypertension. About

I need some help. I have Idiopathic Intracranial Hypertension. About a week ago, I had a pretty serious seizure and was rushed to the hospital by ambulance and spent a week there, having more seizure. They told me the seizures were not epileptic after an EEG, and that they didn't have a reason for them. I'm also left with trouble walking and awful balance, and high pressure symptoms (pain behind my eyes, double vision, blurred vision, pressure feeling in my whole skull.) I have two shunts in my body- one is a ventricular peritoneal shunt that is tied off (it failed) and also a lumbar peritoneal shunt that is supposedly function. At no point did anyone look at my optic nerves, or do anymore diagnostic testing to check my shunt accept xrays and a head ct, which of course was negative, because it's always been negative even when my pressure is high. The seizures still come and they said there's nothing they can do about it. Is it possible that there is a shunt malfunction that they are failing to find? Please help.
