IV Iron
They give me a number of medications while I'm dialyzing. They just shoot the stuff directly into the tubing, saving me from having to take it orally or having to get injected again.
They give me EPO, to stimulate my bones to make red blood cells. They give me Iron so that my bones can build red blood cells. When they inject the iron, I get the sensation that I'm smelling and tasting something. It's kind of like soy sauce but also kind of smokey. Its overpowering and its nasty.
