I more or less came across mine by accident , but I had been reading about chiro care and was considering it.. luckily he was very good and gentle with his technique and happened to be very knowledgeable overall.

I suggest doing web searches in your area and see what kind of websites you find for those near you. If you find a generic looking site or if they say they can fix everything, I'd avoid those.

Look for one with some real information ad a dc that has extra training, uses other modalities like ultrasound, IF stim, low level laser... and perhaps some triggerpoint and massage. The extra upper cervical knowledge is good if you ever had a head hit or whiplash effect. It takes extra training to adjust the c1c2..

If you have recent x rays / MRI it is good to take them so the DC can review, many will require x rays before any tx.
