As a professional, it's important to do your "homework". If you stop and think about it, he's making a statement based on the risks and complications that may occur. It IS his responsbility to tell you this.
As a coach and trainer and posture alignment specialist, I do the SAME thing. I recommend they avoid surgery because....I recommend this supplement or herbal over this because.......I don't do this exercises because.......I don't use this piece of equipment BECAUSE...... THEN, I let the client make up their mind from there. RARELY and I mean RARELY, have I ever in over 30 years had someone not take my recommendations because I feel I give them other options and help them to understand their bodies and what other options they have and the issues they face if they do or don't do this or that.
EDUCATION is IMPERATIVE in the medical, sports and health fields. Are you REALLY willing to risk all of this? Ask yourself if you may risk more complications by "having your own way".
There have been a rare few cases, as a gymnastics and cheerleading coach, that I refused to teach a child a certain skill BECAUSE they weren't willing to learn other skills first. This happened when spring came around and it was time for cheerleading tryouts. It's like trying to teach someone calculus before addition and subtraction. In skills like gymnastics, it's a HUGE risk factor that I would NEVER take personally or for a child. I can only remember two times in over 30 years that people went somewhere else. That was always fine with me. I NEVER, NEVER NEVER, in that many decades had kids with major injuries and VERY FEW minor ones as a result.
That's probably more info than you want to hear, but I'm trying to make a point here. If I were you, I'd be GRATEFUL this doc has the integrity to tell you this and wants to do what is best for both of you. There ARE those out there who would rather take the cash and never say a word. BE GRATEFUL and look into other options.
What if it creates problems that result in you not being about to take care of your kids? Something to think about...
