Brain doctors are very overrated ,, they can pretty much say "i don't know" to every question and get away with it.
Will one surgery be enough? Well we won't know till after the first surgery"
Will this surgery help? Well,, we don't really know"
Can it cause paralysis Well ,, there's no real way to tell"
Will it kill my son? Well,,,, we don't really know"
Trust me try that with any other occupation ,, with EVERY customer.
