I had umblical hernia repair 9 months ago. I had one at the top of my stomache right under my breast and 2 right above my navel. The thing is, my stomache is still swollen and looks really abnormal. It didn t look like this prior to the surgery. Also, as the day goes on, it can get really hard like a basketball. How can I tell if I am retaining fluid, or, what could be the reason why it is still swollen?
