I did ask him about the numbness in my bottom lip, which I am happy to say has full partial feeling! It's very minimal on my right side, but I can still feel pressure. I couldn't tell direction or feel hot/cold when he tested that area though. It was just a tingling sensation that something was there. Which is fine with me. It's possible that more feeling could come back in the next six months since there is feeling there now, so I'll remain cautiously optimistic for now.
I had been having some popping/cracking/discomfort on the left side of my jaw whenever I was eating, and that's apparently just due to getting used to the new alignment of my teeth/pressure from the rubber-bands, so I was prescribed an anti-inflammatory drug, which has worked.
Also, my hair is back to normal. The telogen effluvium literally lasted a month, so not too big a deal.
Anyways, that's it for now. I'll update again when I get my braces off.
