I live in TN and I don't know what happened but i think it's a spider bite..happened about 4 months ago. Itches like hell...i've scratched it so hard that it's gotten to the point where i don't feel my nails anymore.

I can plainly see two little black dots next to each other. not sure you you people can.

the first month it had a knot under the skin and it hurt to walk, like i had pulled a muscle in my foot. but it doesn't do that anymore...just itches like HHEEELLLL!!!

What is it..what do i do??
