If your finger is swollen and painful after being pierced by a fishbone, emergency measures such as extracting the fishbone and subsequent treatment can be carried out to help it recover.
1. Emergency measures: If the fishbone remains in the wound after the finger is pierced by the fishbone, it should be pulled out in time. At the same time, the bleeding in the affected area should be stopped by applying pressure with a clean cotton swab or finger. Some fish spines contain toxins, so the wound needs to be cut open to remove the remaining fishbone tissue and toxins.
2. Follow-up treatment: Generally, alcohol or iodophor can be used to rub the wound after the bleeding stops, and the wound can be dressed with sterile dressing and changed regularly. Meanwhile, for the swelling and pain of the finger, cold compresses can be applied to relieve the pain, or ibuprofen and other medications can be taken to treat the pain; if the swelling and pain is caused by infection, cefaclor, amoxicillin and other antibiotics should be taken to treat the pain.
It is recommended to consult a doctor in time for diagnosis and treatment. Specific drug treatment should be carried out under the guidance of a doctor.
