What are the symptoms of childhood variant asthma?

The main symptoms of childhood variant asthma include: 1. Coughing: This is one of the primary symptoms of variant asthma, typically presenting as a dry cough that may persist for more than four weeks. Coughing often occurs at night or in the early morning and may worsen upon exposure to cold air, inhalation of allergens, or after physical exercise. 2. Chest tightness and chest pain: During an asthma attack, children may experience chest tightness and a sensation of pressure in the chest, and in some cases, chest pain may occur. Severe asthma attacks may be associated with excessive fatigue and strain of the respiratory muscles. 3. Difficulty breathing: During an asthma attack, children may experience shortness of breath, particularly difficulty exhaling. Some children may feel it difficult to both inhale and exhale. In addition, some children may also exhibit symptoms such as white frothy sputum, fever, headache, and fatigue.
