Day 6 of post op for myself and woke up this morning with a tight upper chest. Although it's the same feeling I've had since right after surgery, I did have sips of Hot and Sour soup broth last night ( big hunger craving yesterday but manageable ) and think it may have been too spicy this early into the surgery. The biggest thing I have found that works is getting up and walk. Went to the mall last night with the family and although I was a bit tired, it felt good. Everyone has said the walking pushes the gas. Also deep breaths the minute the chest starts to get tight.
