You perseverate in judging his behavior as rude even though several of us tried showing to you that the situation was comical (as created by you initially) and that he intended to treat you well. Since you created the situation as comical to begin with, it needed an equally lighthearted transition to more serious tone if you indeed did not want him to tease you. What would have helped under the circumstances is a sense of humor. It is not too late, I think, to acknowledge to him that his initial teasing was well-intentioned, that you value his concern for you and his work as a chiropractor who cares for you, and that you you wish you had done two things differently:

- asked him nicely to stop teasing you right when you first felt uncomfortable
- had the presence of a sense of humor when you finally decided to ask him to stop.

In other words, use some self-deprecating remarks.

In my opinion developed over many decades of living, self-deprecation is one of the biggest assets in human communication.
