IS THIS BAD ??? Oo ??

I damaged my big toe a couple of years ago and twisted it a little, never had any trouble with it until last week, my big toe seems to be slightly pulling back and there is swelling under the arch of my foot, my ankle looks out of alignment and a little swollen on one side, and my calf muscle is not as responsive. Their is a little swelling on the outside of my leg, and a big swollen vein running up the inside of my leg to the knee, the vein has a pea sized lump in it on the foot and the full foot is sore but not un bearably painful so i know its not a break, any ideas on whats happening ? thought it was just a sprain at first but it shouldn't be dragging on like this .
