First...you're just a little over a month post-op, which is still very early in the healing process. You may have read us reminding each other that it takes a full 6 months for most of the healing, and a year for the rest. I even found improvements into the second year!
I was told by my surgeon and others that the esophagus is a "dumb" organ, and it interprets all pain as reflux. That's why you're worried that what you're feeling is reflux. If that area was the most painful for you pre-surgery, it's likely that it's quite inflamed still, and will take time to fully heal. It didn't take us a month to injure our upper GI tracts with reflux, and it'll take longer than a month to get things healed and feeling better.
In addition to the inflamed tissue that was there prior to your surgery, remember that your upper GI tract has been assaulted with surgical tools, and it has a right to be angry with you! You have been stretched and wrapped and stitched--not to mention the endoscopy tube, probably bougie to space the wrap, anesthesia, and on and on.
Sulcrafate might be a big help. I have a very reactive stomach and take the liquid form, Carafate suspension when my wrap gets irritated (remember...your wrap is made out of your stomach!). It coats it and definitely makes it feel better. While it's not quite as efficient, if you take a sulcrafate tablet and put it into a small medicine cup or shot glass, then add a little water and stir, you can make a liquid formulation that can do some coating of the area. Once it's mixed as well as possible, throw it back (to bypass your mouth as much as possible) and swallow it down. The idea is to coat the area and help protect it. Once it is coated, try not to drink much water for 10 minutes or so until it's attached to the tissue. Just a thought. I do think it may help.
Keep up with the careful chewing to a smooth consistency. That way your food isn't adding to the onslaught of irritation.
Unfortunately, your surgeon is not alone in underplaying the difficulty and length of this recovery. I hear about it all the time. I've wondered if they fear that their patients will back out if they let them in on the truth, or that they just don't know! They don't follow their patients all that long, and probably go by the eating protocols they were taught during their training and reading.
Again, glad you've joined us! This is a great place for people who've had Nissens!
Hang in there. It WILL get better, but it just takes time and patience. If you can surrender to the path your recovery takes and follow its lead your recovery wil be much easier. Everybody is different, and our bodies react in different ways. In the end, you'll do fine.
Very best wishes,
