I twisted an fell on my right ankle (outter) 2 weeks ago it hurt but I was still able to walk afterward there was little swelling and no brushing after a few days it felt a lot better no pain and no swelling now 2 weeks later the entire top of my foot and both side of my ankle is very very swollen it doesn't hurt to put weight in it or walk but and there is no bruising why would this swell so much after the fact?
