Hi, I am an American Board Certified Neurologist with vast experience in treating all neurological & medical conditions and I am very glad to help you with your health concerns.
You need to be seen by a neurologist or neurosurgeon asap
The symptoms you are having are suspicious for some shunt related problem
It may be shunt obstruction or shunt related infection etc and this can cause increased CSF (Cerebrospinal fluid) pressure and cause the type of symptoms you are having
This needs to be examined clinically and then investigated appropriately asap
You may try to visit the ER and they need to call the neurologist or neurosurgeon to examine you and then arrange for shunt related investigations that will include a brain scan like CAT scan and shuntogram or shunt series etc and once the precise cause for your symptoms is identified it will be treated appropriately.
Please not to be scared, shunt related problems can be successfully treated so try to get this examined and investigated in the ER asap.
