I went to my Neurosurgeon yesterday...the second one in almost 3 years. I had been trying to convince doctors for the longest time there was something wrong with my shunt! So, yesterday I went to my 2nd appoint with my new neurosurgeon and he finally tells me after looking at the most recent MRI's and looking at the spinal tap results there is something wrong with my shunt. I have known this for a long time now. Anyways, I have to have surgery on a shunt that's 27 years old. The nuero is unsure if he want's to just completely replace the shunt or put a 2nd one in. The condition has gotten so severe the ventricles are starting to swell and that's what's causing increased headaches, vertigo, and seizure activity. My shunt is over 27 years old i have had it since i was 9 months of age. Never had a revision. So this is something I'm not anticipating. I've never even had a surgery in my whole life. When something doesn't feel right...it isn't. Trust your gut.
