Assuming you've eliminated chance of under/over draining, can you get in asap to see a really great ophthalmologist to check your eyes? And look at your optic nerve to see if there is evidence of pressure being too high. My kid's imaging stopped showing anything when she's obstructed but she has slit vents. So the standard emergency dept protocol is not helpful for her (and the number of CTs can really be excessive so a neurosurgeon fellow or attending has to order that test). Hope you can get your doctor to order immediate tests (low risk to more if need be) to recheck if there's a shunt/other issue, imaging shouldn't replace their ability to think, although it does for some, too bad imaging is not a perfect method for diagnosis.
