Hiya! It's still very early in your recovery. You're getting into the period of the greatest amount of swelling so you'll feel worse than you did just out if surgery. Discomfort related to healing in your esophagus feels like reflux, but isn't. Your digestive system has been through a lot recently, you'll need to be patient with the weird things you'll be feeling. I wouldn't worry too much at this point unless you are in unbearable pain.
