GWS why! Did I suspect this was your problem or am I a deluded bat, or both?
No, that was me. Why1040 gave me the lurgy on the barakta birthday ride, and I then passed it on to barakta a couple of days later. It went to my both my lungs and briefly sinuses, but I managed to eventually get rid of it with gratuitous over-use of salbutamol, ibuprofen and xylometazoline nasal spray. Barakta, whose sinuses are anatomically 'interesting' so is under instructions not to mess around, was given Augmentin after a week or so, but it didn't do anything.
It was a really rather spectacular lurgy though. I strongly disrecommend it. Left both of us in a state where we had about 2 hours worth of useful brain energy per day, then spent the rest of the time sitting around like snot-producing zombies.
Ob-grumble: I lost a fight with the duvet in the early hours of this morning, and ended up bashing the back of my hand on the corner of the bed side table. It now has a bruise reminiscent of the last time a junior doctor (he was about 12, and trying to Be An Authority Figure) tried to put a cannula in, and I'm hoping it won't end up the same colour.
