Hi! I had what I thought was some sort of bug bite on my forearm. It was a definitive circle, with a hard round outer red circle around it, for a few days. Then the outer circle disappeared and the pencil eraser size bite was still there. Went to the dr and he said it s a spider bite. The inner circle now looks like a cigarette burn. The circle has popped and bled a bit. It s been over a week and I m a little more concerned that perhaps it wasn t a bug bite to begin with. I live in AZ and could have easily been bitten by something poisonous r.....do I go back to the dr or just wait this out more?
