What symptom involves difficulty swallowing?

The symptom that involves difficulty swallowing is dysphagia. This condition can arise from various factors, including neurological disorders, structural abnormalities, or muscular issues affecting the swallowing mechanism. Dysphagia typically manifests as a sensation of food getting stuck in the throat or chest, discomfort while eating, or an inability to swallow altogether.

Aphasia refers to a language disorder that affects a person's ability to communicate, either in understanding or producing language. Paresthesia is a sensory condition characterized by abnormal skin sensations such as tingling or numbness, often resulting from nerve damage or dysfunction. Hemiparesis is a condition that leads to weakness on one side of the body, often following a stroke or other neurological event. None of these options directly relate to the act of swallowing, which is specifically addressed by dysphagia.
