My husband has a sore on his forehead that threw this week has got worse.He thinks it was a spider bit. It does have a little whole where it looks like it could be a bit. Its red on the outer edges and has black in the center. We live in Ohio so I'm not sure if a spider that we seen pictures on line that can do that are here. We dont know what to do for it. He did have some headaches this week to.
