I think if the chiro is skilled, knowledgeable, thorough and precise you should be in good hands. But if you don't feel you can fully put your trust in the care of the dr then might be best to look for another that you feel is trustworthy.

They should be open to more discussion too if you feel you need that to be comfortable with it all before committing to any treatments.

Make it kind of an interview process.

Maybe let them adjust mid back ?? if they feel it is needed before any c spine adjustments ??
or request non manipulative treatments before any adjustments to get a feel for technique and interaction??

Does chiro do only adjustments and no other therapy ??
{US, INF, LLLT, NIMMO etc}

If I ever have to find another DC I think i will hang out in the waiting rooms of any DC I am checking on and talk to the people that are there to see how they feel about the dr...
