otherwise you may want to look into a machine called Pro-Adjuster! i didn't like manual adjustments, especially when they couldn't get it on the first try. and yes, i would cringe and tense up too! but my chiropractor uses this machine and i love it. i sit still and the machine does everything for the chiro, he just guides it & tells it what to do and where!
just a thought. hope things get better for you soon & good luck
