Just a quick update; morning started very well with me managing to eat my entire cooked breakfast (I love the fact that is a good thing) and a nice long walk with the physio being my longest yet and at the fastest pace so far. Shortly after this, I began to get a bit of chest pain and pressure build up and noticed the drain was no longer hissing. Minor panic on my side, and the doctors were nice and calm, came and fiddled about with the drain which obediently started bubbling again. I got a chest Xray which showed that the lung was still fine, however they agreed that it did deflate again a bit when the drain became slightly obstructed as it is still in the position it was originally placed in when the lung was down, therefore now the lung is pretty well up it will bump into it and block it off every now and then (ooh I am so scientific me). I consoled myself by consuming hot chocolate and Christmas cake which had instant and magical cheering up effect (I am my mothers daughter), whilst they went off to have a chat about whether something should be done.
They decided to do a bit of wiggling (of the drain, not of themselves although that would have been more fun for everyone involved) and it all went swimmingly so drain is now slightly adjusted and hissing merrily and I am a tad sore but fine. The best thing I can take from teenytiny collapse is that it was teenytiny, i.e the lung did not throw its hands up in horror at having its drainage site blocked and collapse dramatically on the spot like previous diva behaviour. So it is obviously deciding to stick and play along nicely, yay go lung!
