I've no idea how I managed it.....but I've managed to pull a muscle in my gluteus maximus.
Fore the commoners amongst us, that's arse, or ass, or bum, or butt, or fanny(for US readers, definitely NOT fanny for European readers), or hole.
It's not a constant strain, but a darting pinch every time I lean forward. I now remember that it's there and take appropriate due diligence, but for the last 2 days I've been bending over and hopping back up with an 'Ooooooooh' reminiscent of a rather camp proctologist with a pinching fetish.
It was a source of amusement at first, but now it bloody smarts so it does!
Luckily the 'gettin jiggy' phase has now passed and I can rest my weary bone(s) for a few days , that is until we get good or bad news again which should be somewhere about the 26th.
Santa, I'm f&^%ing warning you buddy....
