It would be VERY rare that a betta would have TB, unless he was exposed to a community tank that had fish with TB in it. Most serious breeders are fastidious about the health of their fish, and the fact that they jar males early on means they are not in contact with other fish.
It's those petshops which keep their bettas in community tanks, that are of more concern.
TB from a fish presents itself mostly as a skin thing initially in humans. If you got a rash or other area on your skin that presents, it would be a good thing to have it checked out. Evetually it could spread to lungs etc. But it can be treated. You just need to be vigilant.
I really don't think you have anything to worry about. He could have been born that way and it is very common for fry to sustain injuries when very small. Several of my guppies have had curved spines, in a tank I KNOW to be TB free. Newly born fry sometimes get stuck between the gravel in my tank. I will carefully remove the gravel with a bamboo skewer to free them but sometimes they do end up injuring themselves from fighting to get free.
