I went and saw David and Chris today they were very friendly , the examination is non invasive , it scans your body through waves and picks up "stressed areas" my stressed areas is were Ive been suffering with my problems .It not only identifies area but gives u a solution on how to improve it , I also highly recommend having your bloods looked at all my symptoms link up as one so I now know where to start in "sorting" myself out , can't wait to go back and check to see if my blood and stress areas have improved, it feels so much better knowing I know have somewhere to start with improving my health ????
