When I was told about NUCCA, I have to admit, I was quite skeptical. The non-invasive nature of the adjustments made me wonder if anything was really happening. I had previously been going to another chiropractor on a regular basis for several years, and was down to monthly visits, but I would definitely start feeling the pain returning at about week 3. I got on a regular schedule with Dr. LeFever, and am now on a "maintenance" schedule of once every 2 months (currently working on an even longer interval in between)!! Both Dr. LeFever and the staff are very helpful and attentive. If you've been battling pain for a long time, this is definitely worth a try!
