Poor advice. Everyone reacts differently. Just because procedure X didn't work for you doesn't mean it won't work for someone else. Conversely, just because procedure Y *DID* work for you, it doesn't guarantee it will work for anyone else.
Even if you do your due diligence and your medical team is capable, there will always be a small percentage of people that have unforeseen side effects or complications to any procedure. While it is unfortunate to fall into that percentage, that doesn't invalidate the procedure.
