Can a fish bone stuck in the throat be resolved with just a glass of water?
Generally speaking, a fish bone stuck in the throat cannot be resolved simply by drinking a glass of water. The detailed explanation is as follows:

When a fish bone becomes lodged in the throat, merely drinking water will not help swallow it or cause it to move on its own. Instead, repeated swallowing movements may cause the fish bone to embed deeper, increasing the difficulty and risk of removal. If the fish bone is large or sharp, it could even puncture areas such as the esophagus or arteries, leading to serious consequences like infections or severe bleeding.
When discovering a fish bone stuck in the throat, one should immediately stop eating to avoid further deepening of the fish bone due to swallowing actions. If the fish bone is lodged in a shallow position, with assistance from family members, you can use a flashlight to illuminate the throat and attempt to remove the bone with tweezers. If the fish bone is deeply lodged but still perceptible, you may try inducing vomiting to expel the fish bone.
If the above methods fail to remove the fish bone or if severe symptoms such as intense pain and difficulty swallowing occur, seek medical attention immediately. Doctors will use professional tools and equipment to perform a laryngoscopic examination, determine the exact location of the fish bone, and safely remove it.
