I was sleeved on Oct 14 and released 3 days later. After a few days at home I began to have chest pain if I took a deep breath. My doctor advised to to continue taking my ppi and increase my gas-ex and this actually helped. However, the pain is now felt in my lower left back area. Again only when I inhale deeply. Besides this I feel absolutely great. No nausea, no vomiting, no fever. I am not on any pain meds. I have regular bowel movements daily. Im getting in all my fluids and protein. Mostly still liquid diet but some applesauce, yogurt, etc. Anyone else experience anything like this?

Yes. It is most likely gas too. I walk it off.
