Is it possible to get a rash/burn on the skin after applying ice/frozen? - rash broken capillaries

Yesterday my son took his head to the supermarket and the urgency, I avoid frozen peas on his head to a large pothole on. Well, 24 hours later, you can not see a play where he was wounded, but it stains pink in the middle of the forehead. What is it? Could a freezer burn 'type of thing? Or are broken capillaries? Help!
