The symptoms of a fish spike entering the trachea are mainly painful at the site of the spike, accompanied by an irritating cough in the trachea. When coughing, the pain may flare up or worsen in addition to the original pain. If a fish spike penetrates the cervical segment of the trachea, pressure on the anterior wall of the trachea on the anterior side of the neck may cause increased pain. If the fish spike injures the mucosa and blood vessels of the trachea, hemoptysis may occur. If the amount of bleeding is large, the trachea may be blocked, resulting in respiratory distress. In addition, a puncture wound to the trachea has little to do with the pharynx or esophagus and does not have much effect on eating or swallowing.
