Some children have a cold that is only caused by nasal congestion, and after symptomatic treatment of such children, they can have good results in a short time. Because the condition of these children is mild and superficial, it is only limited to coarse breath, and there is no clinical manifestation of nasal agitation or even open mouth and raised shoulder breathing. In addition to coarse breath, the child will have nasal congestion and runny nose. If there is wind-heat and cold fear, not only the nose will be coarse, but also the breath may be heavy and the breath will be hot. However, these two kinds of patients are only light, for example, the disease is mild and shallow, and it is easier to treat. Children with coarse breath, nasal agitation, open mouth and lift shoulders, or even have blue lips, suggest that the child’s disease is more serious, and should seek medical attention in a timely manner.
