I have very suttle speech issues not anything doctors would take very seriously. I don't bite my tongue when I'm eating that often, but I think that is because my tongue naturally is further back than normal. When I try to force a normal tongue position my airway gets much better through my nose, and I just feel much better overall. But after doing this for a while, my tongue starts to hurt and my teeth shape is indented in the sides of the tongue.
It's cool to talk with someone with the same problem, because there is not a lot of people who wants to listen or even try to understand this problem, not even my parents haha. I'm 100 percent sure that I'm not gonna go for the chin surgery, because I know that it's not the right choice for me. I hope that you find the right doctor for your case man, it's a long and s**tty process..
Do you have sleep issues? Had a sleep test?
Family can be problematic for some people, defintely was for me when I first tried to acknowledge my issues. Treated me like I was delusional, which is very counterintuitive when the doctors are affirming the very same things I'm thinking. Funny bc my sister had bimax for cross bite etc. surgery five years after my initial consult. At any rate, some times it's better to tread lightly. I should have had braces as a kid, just didn't.
Probably best to just do it all at once. I mean, you would greatly benefit from chin surgery, but ultimately although it offers vast improvement...I don't think it alone will produce the best result. It's definitely a personal investment, but I feel it's worth the struggle. Better to do when you're younger and your healing potential is greater.
