I had a nissan done in 2002. The surgery went great and have had no problems until recently. I can tell that the acid reflux is back as it makes my throat sore and coughing. I am also having really bad bloating ater eating anything! It feels like like my upper stomach is swollen all the time! Does this sound like problems with my nissan? Not sure but seeing here that a barium swallow is the way to check.
