What your friend experienced is often referred to as "globus sensation" or "globus pharyngeus." It is a feeling of having something stuck in the throat when, in reality, there is no physical obstruction present. Globus sensation is a common symptom of anxiety and stress. People who experience this may describe it as a lump, tightness, or discomfort in the throat.
It's essential to understand that globus sensation is usually not caused by any physical issue in the throat. Instead, it is believed to be related to heightened sensitivity of the muscles in the throat and neck, often triggered by emotional or psychological factors, including anxiety, stress, or even reflux.
If your friend's doctor didn't find anything physically wrong with her throat, and the sensation persists or worsens, it may be worth considering anxiety or stress as the underlying cause. In such cases, seeking support from a mental health professional, such as a psychologist or counselor, can be beneficial in addressing the anxiety and managing the globus sensation. Additionally, relaxation techniques, stress reduction strategies, and mindfulness practices may help alleviate the symptoms.
