I too, have a shunt. I've had 7 revisions total. My neurosurgeon told me I have a tendency to build up scar tissue. Does anyone have pain in the back of their head behind their ear that goes down the neck? My shunt is on the rightside of my head in between ventricles 3 and 4. I developed hydrocephalus after birth that is why I have one. I'm also what you call shunt dependent. Without it, I die. I would appreciate any insight into this problem
