It's probably just because you don't run enough. And you may not have warmed up enough before you did it. Take some anti-Inflammitories (Asprin, Ascriptin, Tylenol etc..) and throw some ben-gay or icy-hot on your knees and wrap them. If it bothers you to walk then you shouldn't be walking. Remeber this. R.I.C.E. Rest, Ice, Compression, Elevation. Trust me it will help you out alot. I kickbox and box and whenever I injur myself I want to heal as fast as possible so I don't have to miss out on training. That's what I do and it works everytime..
cold compresses are used for vasoconstriction which means it causes blood vessels to constrict, which is used for trauma, its used when you have say hit your head and an instant bruise or knot, it clots/constricts the blood vessels so it wont continue to bleed and swell in that area under your skin
hot compresses are for vasodilatation which encourages fluid to return through dialated veins to your heart, in his case its generalized swelling because it didnt occur until the day after so he needs a HOT compress
not trying to knock u Example_one but he doesnt need cold in that situation, he would if he had fallen or in your case kicked on his knees or something like that
I know I sound like Doogie Houser but, I'm no doctor I just have 2 Nurses in my life.....wink....wink
either way if it doesnt go away in 24-48 go see a real DOCTOR
