You are evaluating an otherwise healthy patient that has concerns about redness, warmth and mild swelling to the left leg.  He did have a superficial cut to the area several days prior to the onset of redness. Over the last 24 hours, has also noticed increased fatigue, low grade fever and body aches.  On exam, this is what you see (refer to photo below).  What is the most likely diagnosis and recommended first line treatment? The patient has no known drug allergies and is not on any other medications.
