ElI5: Why is it that sometimes (after minor injuries) you can have bruising that doesn’t really hurt, but other times you have areas that feel very sore and aren’t showing any sign of bruising?
In: Biology
Let’s say you fall and scrape your knee. There’s going to be a lot of blood, you’re gonna have a scab for a few weeks while your body works to repair the skin, but it won’t hurt that long. Or lets say a paintball hits you. It hits you so fast that give you just a bit of internal bleeding, which causes the blue/red bruising, and in the process of cleaning that you get some pus that makes it a green/yellow colour.
Compare that to when someone hits you on your thigh with their knuckle or elbow. Then it hurts a lot, but no blood vessels are ruptured, so there no visible bruise.
I’m by no means a expert, so this isn’t the best answer, but i hope it helps.
