Emily Cowley was brought in to the Queen Elizabeth Hospital in an ambulance earlier this morning.
Her foot was caught under a door as it opened and stripped the skin away.
As a trauma case, she was seen quickly after arriving and her wound was cleaned and bandaged. She is now waiting to see a plastic surgeon in the minor injuries waiting room and is expecting to be admitted ahead of an operation.
Emily told ITV News: "They saw me quickly when I first came in and now I'm just waiting, I don't know how long for. I wish I could just go home."
A&E departments across the country are having what some people call "a challenging" time and others say is a full-blown crisis.
Queen Elizabeth Hospital Birmingham is a major trauma centre treating the most severely injured casualties from across the Midlands.
