Almost 17 years ago i had a vp shunt placed in due to brain hemorrhage. i've had it all my life and the doctors said that the surgery is risky. but what are the risks? would it be better to leave it alone? i've tried to google the risks but can't get any facts that i know are true. i want to get surgery so i can finally be able to play sports and not have to constantly worry about getting hit on my head or having to explain to everyone i meet as to why they can't touch my head (due to me being protective and not wanting to risk them smacking my shunt.)

Unfortunately... You're better off keeping that VP shunt in your head. VP Shunts are usually kept in for a long time, which actually can cause a problem where skin and tissue attaches to the tube. VP Shunt removals are risky, because that means, that they would have to separate the tissues that have become attached to it, which can create major complications, especially when brain tissue is involved. You also run the risk of severe infection from doing so... The Shunt removal especially for such a long time period is better avoided, but it is possible, but you should probably bring it up with your PCP and a neurosurgeon or neurologist. 

On the bright side, you can actively participate in sports just as long as it is not a contact sport, which risks contact with the shunt.

It settles nerves, reduces the tension.
