The presence of a whistling or breathing sound from the throat may indicate partial airway obstruction or irritation of the throat or vocal cords, which could be related to smoking or an underlying respiratory condition. A detailed clinical evaluation by an ENT specialist is advised to determine the exact cause. Smoking cessation is strongly recommended to prevent further airway irritation and potential complications.

These symptoms may indicate a viral or bacterial respiratory tract infection, such as the common cold or bronchitis. Management includes adequate rest, increased fluid intake, and steam inhalation to help loosen mucus. Over-the-counter expectorants or antipyretics may provide symptomatic relief. If symptoms persist for more than a week or worsen, consult a doctor for an accurate diagnosis and appropriate treatment.

Your symptoms are likely due to postnasal drip associated with a cold, during which mucus drains down the throat while you sleep, causing irritation and swelling. Maintain adequate hydration and use a humidifier at night to help reduce mucus buildup. Warm saline gargles and steam inhalation may also help relieve nasal congestion. If breathing difficulty worsens or persists, seek prompt medical evaluation to rule out any serious condition.
