Hello I Had Neck Surgery Done A Year Ago June

Hello I had neck surgery done a year ago June 18th at Grady Memorial Hospital in Atlanta and the surgeon didn't put my Esophagus back correctly. Had a barium modified test done and discovered the esophagus is now c shaped instead of straight. How can this be fixed? Have trouble swallowing and cough alot. Thank you --- Ginger gingerr@gmail
