I've never been one for rollercoaster rides. It was never that exhilarating to me when you plummet down that hill with your stomach in your throat.
The day before yesterday was one of Nova's worst, yesterday was one of his best. Today, they call for phone consent to change his picc lines (IV lines, only they actually run a tube into the vein rather than just the needle like a normal IV) changing the IV lines isn't that big of a deal, but the reason they want to change them is because his latest chest xrays came back and his lungs look cloudy, which might indicate an infection.
They don't know yet if there is an infection, they're doing bloodwork and will be super-vigilant about it. Infection would be bad news, obviously. Poor little guy, he's been through hell already. I wish this were easier, more straightforward, with fewer maybes and unknowns.
