So Being post op almost 6 years they pump you full of air so that pain will be there for a few days, walking will help with it. When you have a reversal or a revision it hurts a bit more I felt bad for a week, my wife went through the same procedure and had a ton of pain in the first 48. If you are home and cannot control call the doctor and ask, what the issue can be, I had a kink in the sleeve and it hurt big time. It may hurt now but it is so worth it. 6 years post op I am still loosing and take your vitamins when you are able too, Anemia is a horrible side effect.
