Retained foreign body has ongoing inflammatory potential
Persistent symptoms prompt imaging and re-exploration
Ultrasound most useful adjunct
Natural history guides follow-up intensity
Most resolve within weeks without complications
High-risk hosts need closer surveillance
Patient Discharge Instructions
copy discharge instructions
Home care after stingray injury
Wound care
Keep wound clean and dry

Follow-up appointment
Wound check in 48 to 72 hours
