I had an encounter with my crossbar about 200 metres before I got home yesterday evening. This one's higher than any I've had before, so it's the first time I've properly thwacked it and, um, I could do with knowing how long my crotch is going to be a no-go area. How long does it take to recover, and is visible bruising likely? (At the moment I can just about feel the soreness without any pressure on it.)
