Have been having problems with bowel. (not working at all).Have been on miralax for 3 months 3 to 4 x a day. My Cf doc referred me to a GI doc and he did a colonoscopy , EGD , complete abdominal scan , x-rays to check for blockage. And they still didn't know what is causing it . Didn't go back to the GI doc . My brother talked me into going to his Chiropractor on Wednesday b/c of the back pain i'm having, said it could cause the problems I am having. I was really sceptical about going . But the x-rays showed that I have twisted vertebrates in the lower part of my back and the upper. Can already tell a difference in the bowel part after 1 visit. He said that my nerves are pinched off to the colon. I am looking foward to getting off the miralax .
