Morgan Hungenberg, DO

A mildly overweight 8-year-old Hispanic female in rural Colorado is brought to her primary care provider’s office with right neck pain and right-sided neck swelling of a day’s duration. The patient’s mother also stated that her daughter had a maximum temperature (T-max) of 102°F that started that morning. The patient denied any sore throat, rash, headache, rhinorrhea, cough, nasal congestion, abdominal pain, vomiting, or diarrhea. What's the diagnosis?
