Is this a rash or bites?

Patient: Hello, I seem to have a small rash on the bottom of my leg, just above my ankle. Though, it’s not a red blemish but more like a bunch of tiny bites that are all restricted in one small area. I’m not sure what it is? My leg was itchy the other day so I scratched it and that’s when I started seeing those little bite-like things.
