For a 4-year-old with a history of red itchy skin patches and allergies, how would the cough typically present?

In a 4-year-old with a history of red itchy skin patches and allergies, the cough is more likely to be worse at night due to the presence of underlying conditions such as asthma or allergic rhinitis. These conditions can be influenced by environmental allergens that are often more prevalent during the evening hours, potentially leading to increased airway inflammation and bronchoconstriction, resulting in a more pronounced cough.

A cough that is consistent throughout the day may not reflect the typical pattern associated with allergic or asthmatic conditions, which often have a variable nature. While exercise can trigger cough in children with exercise-induced bronchoconstriction, it is not limited to just that scenario. A nocturnal cough every night suggests a chronic underlying issue that may not allow for periods of relief, making it less typical for episodic conditions often associated with allergies.

Thus, the presentation of a worse cough at night aligns better with the clinical picture of allergy-related respiratory issues, making it the most likely scenario for this child.
