I have eds and can't imagine living that long without being dxd. I think most people are unofficially diagnosed by their twenties. I say unofficially because the testing is very expensive and hard to get. I was obviously hypermobile and a chiropractor had to tell me.. so then I mentioned it to the doctors and they were like "oh yeah"
He must've had jaw work done. Getting just teeth stuff wouldn't cause that. We have a super high tolerance for pain.
If anyone can touch their thumb to their wrist...don't get surgery!!!
