I am on my 3RD MR within a year. I took binder off and I have a larger upper hard abdomin. I also had my belly button reattached. What can I do to get this swelling and fluid down . I am one week post op and I am up 10 pounds which will not go down. I am drinking water. Moving around . low sodium foods. And resting. I have 2 drains on me. I am worried about my upper stomach any suggestions?
