It really depends a lot on the person you go to , same as doctor, mechanics etc..

A very good, expert, highly skilled is always best. Take the time to search out those.
I've been to 2 , an older guy that was very gentle and an overall healer type, he helped me the most with my chronic RSi/TOS stuff. And last year a younger gal for my lower back, she was very gentle and precise as well.
No grab and crack stuff at all from either of them.

You can usually ask for an assessment, no adjusting and see what they say, but still find a a highly skilled practitioner.

There was a member that thought they had RSD years ago , but finally went to a chiro and he found a nerve in her foot was pinched all that time.
