Somehow, I’ve managed to live without breaking any bones, twisting anything, spraining anything - I’ve avoided injuries greater than scrapes and cuts.
And then last night I fell, and hit my knee. Hard. And it did get swollen. (I iced it and elevated it, and rested it more than usual (though not entiredly)). Most of the swelling did go down & if I do look at just that leg, I might not even notice anything wrong at all (but looking at both together you can tell that one is swollen). & it doesn’t currently hurt unless I poke at it (which I’m mostly avoiding).
But, I was wondering - why swelling? What’s going on under the skin that would make it puff up like that? Will it go down completely - and how long does that usually take? Once it does go down completely, is there going to be a permanent bump there or will my leg look normal again? Since it doesn’t hurt, do I need to see a doctor (would I know if it were broken?)?
