Update 6 - X-ray Clear

Just had a very quick phone chat with Kat's mum, and the X-ray didn't show anything, which I think is good. However, her breathing pattern has changed, and it apparently resembles subtle hiccups, because she isn't gasping when she inhales, but her body shakes a little each time she draws in air.

That's all I know at this stage, so will sign off until I hear more.
