Hi
I have about the same thing. It's a result (for me) of abt 8 surgeris on the left foot. with the nerve problem, You may want to ask your doc about RSD (reflex sympathithic dystrophy) I have it. one of the signs is excessive nerve pain, and swelling, different colors, etc. It is worth a question. I have it, and if you want to know more, then check out these boards but under RSD. It will give you an idea of what it is like. Hope this helps
