@Stronger2012,
What do your doctors say when you ask them? They are the medical experts - we are not.
This A2K forum is not set up to answer such questions. It would not be ethical even if there were medical experts here to provide such answers.
We are a group of lay people ...just like yourself (more or less) not a think-tank...who can point you in a direction where you might find answers. The most logical place as to meet with your doctor and ask them directly.
For those who are curious what a
VP Shunt is, Wikipedia is a good info resource that explains in detail:
