Hi Salim, Welcome to HealthcareMagic Forum.
VP or Ventriculoperitoneal shunting is surgery to relieve increased pressure inside the skull due to excess cerebrospinal fluid
on the brain which leads to hydrocephalus
. The headache and eye pain
may be due to various causes, like Excess CSF leakage, Infection, Ventricular collapse. Kindly consult his team of Neurologists and Neurosurgeons so that they can examine him and run few blood test
and if necessary get a CT Scan
to rule out any pathology. Kindly don't worry, once the cause is found out and treated, his problems will subside.
I Wish him Very Good Health, Take Care.
