I'll tell ya why he sold you the world pre-surgery, on your potential recovery post surgery.......he didn't have your money yet.
Now that you've paid him, he'll tell you what he really thinks.
I'm going to offer a suggestion on some stuff for you to study. But before I do, I want to say, that you will likely encounter people with zero knowledge, and absolutely no experience on the subject, who may try to convince you that it's not worth spending any time researching this area. But just keep this in mind, those people have ZERO experience, so is it worth taking their advice.?
It's really simple too. The foods we put into our bodies will build them and repair them or do the exact opposite. That's the simple bit. The difficult part for some people is taking that leap of faith to experience it, and letting go of everything else. But I'm going to tell you exactly what your doctor won't....your body has an amazing ability to heal. Especially at your age, you have the potential to see dramatic changes for the better.
Look into Arnold Ehret, Dr. Robert Morse, Loren Lockman, Dr. Douglas Graham.....for starters. There's so many more, but IMO these few will keep you busy enough and give you the knowledge you need to begin.
Here's a short story from one of Dr. Morse's patients. This man was in a car wreck something like ,15 years?, before he met Dr. Morse. During the wreck his right femur was broken quite severely and it never healed properly. It actually fused back together at a 30 degree angle. Well fast forward 15 years to when he met Dr. Morse....10 months into following Dr. Morse's suggestions the femur straightened out.
Simple story, but this type of thing, "actual healing", is very common to people who choose this path.
One more thing I am going to suggest you look into is an herb called, comfrey, it's aptly dubbed, knit bone, and with good reason.
Even without changing your eating lifestyle, I imagine you will see significant improvement with this herb, if you do the research on it you will see why I say this.
