Oh Lori, I'm so sorry that you and your son are going through this difficult time, I am sending positive thoughts and prayers for strength your way. I totally identify with the white coat syndrome, I am not a stranger to passing out in medical/dental situations(!).
Just a thought, have you ruled out chiropractic treatment as an alternative option? That worked very well for my brother but he was younger, I think 11 years old when he and my mom chose a course of chiropractic treatment over the brace, and I don't know how severe his case was compared to your sons case. It took a couple years of regular chiropractor adjustments, special exercises and nutritional supplements but my brother came through it just fine.
wishing you both the best of luck for a speedy and safe solution,
Nik
