Tyler Rogers3, yes, that sounds most likely like ascites. My mother dealt with that herself due to pancreatic cancer. That pathological fluid doesn't just vanish on its own; it requires paracentesis to drain. Mom was taking Fursemid, but even that didn't provide much relief. It made breathing incredibly difficult because the fluid pressure was pushing against her lungs and other organs, so we had to have her undergo drainage procedures constantly.
