If a small fishbone is lodged in the skin, you can try to squeeze out the fishbone, but if this is not effective, please seek medical attention. After a fishbone is lodged in the skin, you can first rinse the wound with running water, and then observe the wound to confirm its location, depth and number. You can try to squeeze the fishbone out by applying pressure from the periphery to the center of the wound. If squeezing does not work, go to the nearest hospital immediately and have the wound treated by a healthcare professional using specialized tools. You can use tweezers to locate the fishbone and pick it out after you have been prepared with disinfection and anesthesia. If the fishbone is too deep, the wound can be cut open to locate the fishbone and remove it. After removing the fishbone, disinfect and dress the wound again to prevent infection. In addition, for bleeding wounds, tetanus antitoxin should be routinely injected to prevent tetanus, and the wound should be disinfected with iodophor on a regular basis. If there is redness and swelling in the wound, antibiotics such as amoxicillin and cefaclor should also be taken for anti-infection treatment. Drugs should be applied under the guidance of a doctor.
