My fiance had his nissen fundoplication surgery a few months ago and ever since he has had really bad chest pain and has developed an anxiety disorder because of it. Does anyone have any recommendations to relieve the chest pain? He has tried different foods and kept a food journal for a long time, but he couldn't figure out what his "triggers" were. It seemed to be more random then anything else. He has also had trouble with constipation/bloating which makes the chest pain worse. his pain has now even spread throughout his upper body because he is so tense all the time. I would appreciate any suggestions to help relieve his pain!
