I might be overreacting but I'm not sure. Does this look like some type of infection? It started off as a tiny scratch but it has spread. She hasn't picked at it or anything. I know the picture is kinda blurry.

So I took her to the doctor's and they prescribed her an antibiotic. I started giving them to her yesterday so I have to give it time but look how big its gotten! I feel like taking her to the ER now.
