You can always do a Google search for 'chiro in < area >' and see ratings and reviews as well. Don't have any info on your issue but remember chiro deals with joints which in turn are held in place by muscles and fascia which is in the realm of physiotherapy. So any particular issue could be due to just joints or muscles or a combination of both.

Take things one step at a time... Do a consultation 1st. Depending on how the chiro/physio does the explanation., you can then decide to go ahead with treatment or look for 2nd opinion. Consultation usually not too expensive. Bring an xray if you feel your case is complicated. If your problem has been for some time, then you may need more than 1 session but getting over that 1st session is the biggest obstacle... better than surgery though! The chiro/physios also have some helpful therapeutic machines. Just don't feel pressured to buy packages though.
