I am three days post op. Yesterday when i removed my dressing an got to se my stomach I was very happy. It was tight and flat. We by yesterday evening my lower abdominal swelled up like a softball was in there. IT has not changed or gone down at all. It feel very funny to the test. Is this normal? Ive been very upset and scared. I called my PS and they said it was probally normal but if I felt more comfortable I could go in on Saturday.
