But honestly, that can be a win. A good process (with a person you resonate with) can go further than a medical degree. Personal opinion, based on lots of experience.
If a fitness trainer started throwing around things like "clients reported reduction of sciatica symptoms" you would of course assume they are licensed physical therapists and that you are treating sciatica. They could just as easily say "pain management through exercise" and not get caught in that kind of credential limbo.
