Have I got news for you

Busy morning answering calls from the hospital cancelling treatment appointments only made yesterday, but hey-ho I am retired with nothing better to do. The most recent blood test (I have reached the Tony Hancock "empty arm" stage, confirmed by an inexperienced blood removal nurse ) reveals I still have a small infection within my body ( surely not the leg?) by the way, the more experienced nurse eventually found some in the other arm. What is their official title?  I always refer to them as Dracula.
