Today Sam had a dye study to try and discover the source of the leak into his lungs, it involved the unpleasant experience of radioactive dye being injected between his toes on both feet, and then waiting for it to track up the body to the chest. What was meant to be in and out in less than an hour, ended up 3 hours as the dye took a lot longer to get to the chest than expected. Sam was an absolute star, he had some anaesthetic before the injections and then had to lie still strapped into the scanner for hours. Fortunately he had endless episodes of Rory the Racing Car to keep him distracted, but everyone was so impressed with his bravery and patience during such a painful and drawn out procedure. I was very proud of my 'bro', he was such a little trooper today!
Unfortunately the study results were inconclusive so next step is an MRI on Monday, followed by exploratory surgery the following Monday with a camera to try and find the source of the leak. So no end in sight for this admission but Sam is dealing with it in his usual cheery and entertaining manner.
