I can tell you that they did nothing medically wrong. 99% of people returning from this surgery have PSYCHOLOGICAL issues with returning, not physical issues.
So yes, they did do everything perfect. Or at least from the information we have. And I'll act like it because I know it. YOU can act like you know it, but you don't. And that may sound harsh, but it's really trying to watch for people like me in this profession, having anyone with access to google or anyone's just general opinion telling you that what you've studied, what you experience on a daily basis, is wrong because of your own gut feelings.
