Scab Keeps Getting Bigger
Image submitted by Michael, About.com Guest

About.com guest Michael submitted this picture of a large scab:

It was a sore, then it turned out to be a mass scab. Then I went to the doctor and they said they don't know what it is. I have no idea what it is but people are telling me it's a spider bite.

There's really no way for Michael to know what it is without some tests. Even then, there's no guarantee a doctor could identify the cause.

Is it a spider bite? Nobody knows, and I think that's the message Michael should be hearing.
