((((((((((((HUGS))))))))))))).
I'm sorry you're having such a hard time. Unfortunately, hydro is one of those conditions that necessitates repeat surgeries for nearly all of us. Without surgery when you start to fail, you will very likely die, and depending on the reason for the shunt failure, it can take months or hours.
Please re-think this! Death from progressive hydro is the worst kind of torture.

You
do not want to go through that. One lousy surgery experience does not mean all your others will be. It sounds like your previous nsg may not have had as much experience as he should have. It's not uncommon to see more than one nsg before finding one you like and trust. Just don't give up!
