Sorry to hear your in so much pain. It could be many things e.g. that moving the stones has moved a lot of toxins through your body in one go or you could have some stones trapped in your colon that are pressing on your back. Did you do a colonic after flushing? this will help to get the toxins out quicker and lesson the chances of them be reabsorbed by the body and will help to move stones that are stuck in the colon or trapped in colon pockets.
