==Evaluation==
*Diagnosis is clinical
*Consider labs, [[blood culture]] if patient is immunocompromised, risk factors, renal dysfunction
*Bedside [[Ultrasound: Soft tissue|ultrasound]] to identify abscess
*CT can identify deep, extensive infection that involve soft tissues of neck or pharynx

==Management==
#Analgesics
#Remove foreign bodies from affected area if possible
#Abscesses should be drained
#Antibiotics (see below)

===[[Antibiotics]]===
{{Cellulitis antibiotics}}

==Disposition==
*Most patients can be treated with oral antibiotics as outpatient

===Consider admission for:===
