Hello! Such symptoms can be so-called pre-asthma, at this stage children are often diagnosed with bronchitis or tracheitis.
Continue with the treatment prescribed by your doctor.
There are certain tests to diagnose asthma. You need to pass a biochemical blood test for the level of total protein and conduct a sputum analysis (in asthma, it contains Kurshman's spirals and Charcot-Leiden crystals, as well as a large number of eosinophils and neutrophils). Also, a chest x-ray can help in diagnosis.
There are also special diagnostic methods: allergic tests - intradermal injections of various allergens, this helps to identify the allergen that provokes asthma attacks, and peak flowmetry, which helps to assess the volume of inhaled and exhaled air. With asthma, these rates decrease.
