People must be careful however.......A doctor damaged my spine when I was only 27 years old, and I have never been the same since......3 surgeries on my spine (so far if doctors have their way)....Tried Chiro, Physio Therapists, acupuncture, bio feedback and a whole lot of various drugs given by these 'professionals' , a few which have since been removed from the shelves, as they were in fact killing or hurting people........If you just have a few muscle problems I would say..."Go ahead", but if you have the least suspicion there may actually be something wrong in there, please make your doctors take proper pictures of your spine....We only have one spine, and when they damage it ( or if we do ) there is no way to get another one lol........Please never assume because these people we call doctors read a bunch of books and take a lot of exams, that they actually KNOW anything...They know a fair bit 'about' the thing, but no actual experience...It's kind of a really sick way to go about things, having those people in complete control of our lives, as far as whether we are allowed pain relief or not, according to them ! Pitiful !
