Is it hot to the touch? Are you running a fever?
No fever, and if the swelling on my hurt shin is any warmer than my other shin, the difference is so slight it's not immediately noticeable, if at all (though it doesn't help that I sit with my legs folded constantly). The skin above the swelling feels weird when I touch it, kind of like a numb feeling, but not really. When I press it, there's hardly any pain, but it feels weird, like pressing down on a water balloon.
And when I say 'balloon' I don't mean spherical, like a grapefruit. It's long, running up my shin where the scrape is, and it's not even raised enough to be immediately noticeable unless you actually stop and look at the leg. But I sure as hell can
feel it. Sometimes it almost tickles when it shifts, it feels so weird.
