If you find that you have accidentally swallowed a fish spike while eating, follow these instructions: 1. Stop eating immediately, especially if you swallow large mouthfuls of hard food. (Otherwise, it will make the fish piercing deeper) 2, immediately eat some coarse fiber vegetables, which is effective for the smaller fish piercing. (For larger, deeper fish sticks are not effective) 3, you can drink small sips of cool boiled water, (do not drink vinegar) to feel the pain like pins and needles when swallowing. (The acidic liquid will cause new damage to the traumatic surface, and it is impossible for the vinegar to stay in the pharynx, so it will not soften the fish spike) 4. (A fish spike that stays in the throat for too long can lead to local infection, and a fish spike that is too hard can also cause other undesirable complications.)
