Is this a spider bite, or something else I should worry aboutt?
I just came across this... thing.. a couple days ago on my thigh. Is it a spider bite? I live in colorado, but not in the mountains. It does not hurt, it only itches. It is not an open wound, it is the texture of very dry itchy skin. The middle of it is white, and it is surrounded by red. Is it something else? I need help. Sorry if the pictures are bad, it isnt easy to take a picture of something on the back of your thigh.
