"I first want to say the Dr Mark Nightingale he did what 80% doctors don't do he listened to the patient he said there on the bed next to me he'd listen to every word I said as long as I didn't take too long like saying the same thing over and over and then he examined me and if he was not touching the spots that did not pertain to what I was saying he allowed me to show him and I walked out of there with a completely different feeling I have been suffering for 6 years losing weight from 240 to 167 standing six six so skinny I'm about to blow away dying the first visit he said my life I appreciate him so much to the point if I saw him I would break down in front of him and shine his shoes he probably wouldn't let me lol but from what he did to me I know I will have 100% recovery after 6 years of brutal pain thank you Mr Nightingale can't wait till my next visit thank you very much Vincent l Jones"
