Sesamoiditis...

Yes. It is a word. It is used to describe either a broken or inflamed part of your body. No, nothing gross. Sesamoids are the two little bones between your big toe and your foot that are not connected to anything. It is where you put most of your weight when you walk. Apparently also when you sit, since after 27 hours of mostly sitting on airplanes it is back with a vengeance. Nothing to do but tape it in and take it easy. It should have come back on a beach destination, not Sydney.
