.My foot started to itch right on the arch of my foot. The spot got a little red and i thought it was a bug bite. But then it swelled up more and now it feels like i may have worked that muscle too hard and it swelled up. It doesn t hurt at all but it kinda feels like a swelled muscle. I work at a daycare and instead of wearing sneakers i wore Nike slide on shoes. And my feet were killing me by the end of the night. Could that be why my foot is swelled?
