Ok. Im not sure if a leak can happen this late after surgery, but you have consider what kind of method was used to seal your stomach. Was it staples or was it stiches? Because the risk of late post op leak is possible if staples were used to seal the stamch instead of stiches. I have read journals where a leak was reported more than a year after surgery. Please know that i am not trying to scare you. Im just saying that it is better to be safe than sorry. When i had my oubt, i had it clarified immediately by going for a CT scan. Your said symptoms all point out to a leak, Shoulder pain, heartburn, Pain etc. Please consult your doctor immediately. I was sleeved on Jan 2, 2014 and im really looking for feedback on my problems with people who has done this surgery before. I hope everything works out well for you. Good luck
