I had the same thing! It then progressed to throwing up everything...food first and then everything. I went on for further testing and had to have my gallbladder removed. Don’t wait, follow up and get some further testing if you need it. Good luck!
Be careful that you are not pushing yourself too hard around the house. I am 5 weeks post- op and I remember the days I tried to do a little extra and regretted it the next day. One way that I helped relieve the gas pains was with a heating pad. I had pain on my left shoulder and chest and I would lay a heating pad or hot water bottle there. It helped a bunch. I hope you feel better and remember you just had major surgery and to ask for help!
I had my sleeve on the same day and have the same problem. I also had a hiatal hernia fixed at the same time as my sleeve and I am not sure if that is part of the problem. I did talk to my doctor about it and he told me that it could still be swelling from the surgery. Good luck, I hope it gets better for you!
