Yesterday I got into a minor car vs. bike accident (totally my fault - the pickup in front of me stopped suddenly and I was following too close and going too fast). I was on the bike, and I didn't fly over the handle bars but I did swing sideways off my seat and contact a truck tailgate with my shoulder, hard enough to dent and crease it.
I have lots of soreness and what feels like interior bruising, but no outside discoloration. I hardly ever have discoloration on the outside, in fact. It's not always true - earlier in the week I banged my knee on a rock, and there was a minor but widespread bruise. Is it a matter of having more padding on my shoulder and upper back than on my knee, or what?
Do some people just not bruise easily?
