I am approaching 3.5 months post Nissen fundo. A couple of days ago I had an exercise session and now have a fairly constant aching/sore feeling at the wrap site which then refers down the esophagus. I am worried that I may have loosened the wrap/made it slip. My surgeon said I could return to normal exercise at 3 months, including rugby (he said many patients resume normal activities much earlier but that he likes to be super careful and hold off until 3 months) so I assumed I was ok to be more active. It wasn't like I was doing any heavy lifting, but I suppose I was activating my abdominals and stomach in a way they haven't been used in previous months. It is a nagging soreness that won't go away. Has anyone experienced similar symptoms post exercise?
