I got that only the other week, Riki. But I still got a treatment but with only one needle.
They threw all the 2-needle tubing and dialyser away and replaced it with single needle tubing and a different dialyser. I guess it wasn't as efficient at clearance as two needles, but I did get the same water clearance.
That's what they did with me, but they let me go home and come back the next day for treatment, to let my arm heal a bit. My unit is pretty good with squeezing people in. When I wanted to go to Hairspray last week, they actually called me the day of the show and said I could go in early, so that I'd be off with plenty of time to go to the show
