according to some books I read direct adjustment of spine is almost never necessary, its enough to fix the trigger points in muscles. I just went to one chiro to check my spine and of course he said I need major work, at least 6 visits and then some even more...no wonder money talks...
what is the truth, hoe many visits should be necessary if at all? anyway I'll never go to chiropractic again.
p.s.
read trigger point therapy and you'll understand.
