I recently developed a strange burn like rash on my forehead. At first, I thought it was a big zit forming, but it continued to grow bigger. It feels like a burn and looks like a burn but I never burnt myself, and it's been there for a week. I'm wondering if maybe it is a spider bite or something. I really don't know what to do about it, and it's not going away. It's pretty raised, oddly shaped, red, bumpy, burns, and hurts if I touch it. Please help me out. I really don't want to go to the doctor if I don't have to.
