A foreign body lodged in the finger but the wound has healed, if there is a combination of symptoms such as localized pain requiring removal of the foreign body, the foreign body is mainly removed by surgical incision. A foreign body lodged in the finger may cause local infection or local irritation signs. If removal is necessary, it is recommended to go to the hospital, and self-removal is not recommended, especially if wooden spikes, bamboo sticks, etc. cannot be removed intact, which may lead to recurrence of the disease. For foreign bodies with shallow depth, they can be removed without incision, using forceps, etc. After extraction, the wound should be carefully examined to make sure that no foreign body remains, and then properly sterilized and bandaged; for deeper foreign bodies or foreign body debris left inside, incision and debridement may be required, and tetanus vaccination is recommended. In the case of a foreign body left in the tissue, it is recommended to consult a doctor promptly.
