I sprained my ankle last week. The last couple of days, I've noticed my ankle is still swollen and there is a bruise forming at the base of my toes, topside of my foot. It's about 1/2" wide, dark in color, and located right behind the three middle toes. There's quite a bit of pain when I flex my toes. I've been walking flat-footed on that side -- which gives me an odd limp, because it looks like I place most of my weight on the injured side. But it hurts to curl my toes to take a natural step. This area wasn't x-rayed; my foot/ankle was x-rayed much higher up. Is this bruising anything to worry about? Or will it go away with time?
