Fish spikes can heal themselves if they are small or superficially lodged, but not if they are large or deeply lodged. If the fish spike is small and soft, it may slide into the stomach with the esophagus and does not need to be treated at this time. If the fish spike is shallow, cough gently in a bent-over position and use the airflow to cough it out; if there is someone around, have someone hold a flashlight, find the fish spike and remove it discreetly with long tweezers. If the above methods do not work, do not just wait for it to heal itself, but go to the ENT department of the hospital as soon as possible and leave it to the doctor. For deeper and larger fish spikes, the patient may experience pain, pinching sensation when swallowing, and repeated spitting of saliva, etc. In this case, you should stop eating immediately to avoid the fish spike from cutting the esophageal mucosa in the eating situation, and you should also go to the hospital to have it removed by a doctor through a laryngoscope or esophagoscope. When a fish spike is stuck in the esophagus, do not swallow large pieces of buns, pancakes, rice, etc. to force the fish spike down, so as not to push it deeper or cut the esophagus and blood vessels.
