Fish spines are essentially fish bones with calcium as the main component. There is no substance in the throat that can digest fish spines and they will not melt away on their own, so it is advisable to seek medical attention to remove them promptly. Tiny fish spines usually get stuck in the tonsillar fossa, the root of the tongue, the pyriform fossa and other parts of the throat. There are no digestive glands in the throat that can secrete digestive enzymes and acids. The mouth contains digestive glands, which mainly secrete amylase. The main component of fish spines is calcium, which cannot be digested by the mouth and pharynx. In some cases, tiny fish spines can be swallowed and digested in the stomach. If the fishbone stays stuck in the throat, it can cause a tingling sensation and may lead to infection. It is recommended to seek medical attention and have it removed by a medical professional using specialized instruments.
