I hope he keeps getting better. He was very active before. He lives on his own, drives everywhere, etc. So, it's weird to see him homebound, and unable to walk without bracing on things.

I'm not exactly sure what's wrong. All I know is he had some fluid on/in one of his lungs, and something with his kidneys. He said he's been taking pills to make him pee a lot, and the doctor told him not to drink a whole lot of water. So, I am assuming they're trying to get rid of some fluids... for whatever reason. I mean, fluid in a lung can't be good. I understand wanting to get rid of it. But I'd like to know WHY or HOW the fluid came about...
