I, personally, don't like going to an appointment and being surprised by what happens.
To help mitigate that, here's a couple YouTube videos of an ABC Practitioner (who is a Chiropractor, which I am NOT),
Dr. Jeff Aberle, showing what a typical visit will look like.
Take a look and see what's possible for your breath and body!
