this sounds life threatening to me, you could develop peritonitis or septismia both very bad...dont mean to scare but i would demand answers from the doc. if you are feeling very bad keep bothering the hospital....they will have no choice but to treat you
This condition is called ascites. I'm sorry you are so uncomfortable.

I would definately keep bugging the hospital, this really doesnt sound good and I recall reading your post a few days ago about this and you've been suffering with this for too long, I really hope you feel better! Good luck
