Hi Cat,
Your worry is understandable! However, you're most probably experiencing dysphagia, which feels almost like reflux. Remember that your poor esophagus has been traumatized by the procedure. The worsening of the discomfort may be due to the peak swelling, which reaches its peak exactly around week 2-3. I also thought that my reflux was back, because of all the gurgling and the food coming up etc. Unfortunately, the healing process is quite long, but in about
a month or two you'll be feeling better. The PPIs will definitely speed up the healing and lessen your discomfort.
