I have known trigeminal neuralgia (bilateral) for which I have gone through several surgeries on the right side in 2011 and 2012 and 1 surgery on the left side in 1995. I also had meningitis from a shunt being placed in 2011. I have been experiencing the feeling of fluid running along the inside of the side of my head. What could this possibly be?
Thank you for asking Chat Doctor. My name is Chat Doctor.  As you underwent shunt surgery you might be experiencing CSF running in the shunt... As the shunt might be ventriculoperitoneal shunt which is placed subcutaneously placing ventricular reservoir under scalp and peritoneal end in the subcostal region. Due to passage of excess CSF from shunt reservoir to peritoneal the pressure exerted by CSF in the shunt tube. Hope this may help you. Let me know if anything is not clear. Thanks.
