Evaluation
- Clinical diagnosis, based on history and physical examination
- If unsure, see Pediatric Fever
Management
- No specific therapy for most; self-limited
- NSAIDS and cool liquids for pain
- Encourage good hand hygiene to prevent spread
- Some recommend Magic Mouthwash/oral lidocaine if not tolerating PO intake, although evidence suggests no better than placebo[1]
- In infants, do NOT use oral lidocaine due to risk of lidocaine toxicity and FDA black box warning[2][3]
Disposition
- Discharge
- Admit for dehydration or development of complications[4]
Complications
- Some children get a desquamation of the nails around 2 weeks afterwards (self resolves)
- Meningitis and encephalitis are uncommon, yet still possible complications[5]
