Welcome to the Healing Well Wrapped Club! Glad to hear that things are generally going well for you post-op. I can tell you what my surgeon told me when I was at your stage of recovery; "Pretty much anything is possible during the early weeks..."
I don't know if you have already read my early recovery journal...it's in the Resources section...but just in case you haven't seen it, here it is:
As you read it you'll see that it's common to have lots of difficulties and discomforts with eating at your stage of the game.
I used to get a feeling like I was swallowing a huge bubble of air when I ate a bite of food during the early stages. It was very painful.
My guess is that you're getting some food and drink held back at the wrap site due to residual swelling. That's likely the source of the foam and discomfort. As the swelling continues to diminish your swallowing will improve.
Remember that it takes a full 6 months for most of the healing to occur, and a full year for the rest. I found fine-tuning of my upper GI tract continued into the second year.
Hang in there. You're in the thick of the healing process. As time goes on you'll gradually notice improvements. Sometimes just a week is all some things need to resolve.
I'm glad you've joined the forum! It's a great place to be during your recovery.
