Oh NO Julie!! That looks very deep and painful. I REALLY think I would go to a doctor and get some antibiotics for that. I mean KNOW I would and I HOPE you will please? It looks very deep and very likely to become infected. Can you do this please??

I am sure you already know but the first thing it needs is plenty of scrubbing with soap and water and then some ice for the swelling. Then, a doctor.
