I have Stage CKD. Been having painin myleft chest. The Physician did a ecocardio exam and the heart seem to b enormal. Last year a stress test and it was ok. Curren tly a x-ray showed a nodule on my lung. A second exray said that it was a shadow or a blood vessel, I do have chest disconfort and it feels like a puncture in the back of the lungs and the chest feel somewhat like a weight has been placed on it. This pain and disconfort comes and goes. Does CKD cause these type problems, and if not any ideas. Thank-You Fred
