How much pain are you in?
I had my surgery the 5th and the 1st week was terrible but after I got the drains out it got better every day. It sounds like you have pain or pressure from being too full or having alot of gas?? I had to re-learn the feeling of being full, it felt more like a big painful knot in my chest just below my sternum, when I asked my friend who has been through it and figured out what it was I don't have the problem anymore. I hope this was helpful...Good luck and take care...p.s. also remember not to lay down when you've just eaten and sit up when you drink anything or else it can be very uncomfortable and sometimes cause vomiting.
I'm one week post-op today. I'm up and around and sleeping OK. I'm taking tylenol for discomfort but not really pain. I get crampy when I eat or drink and I'm very protective of my tummy area (I have a 4 year old *****ally misses climbing on mommy!). I would say I get a lot of air rumbling around just below my sternum that sometimes gives me a twinge (especially when I just wake up in the morning and don't have anything in my system for pain relief) so maybe it's similar but causing you greater pain.
