Characteristics of growth fever

Many children may develop some physiological characteristics during their growth period. These physiological characteristics require vigilance and corresponding preventive measures. Patients with growth-related fevers show symptoms that are no different from normal ones. The fever will not last too long, generally lasting about 1 to 2 days, and may be accompanied by body pain, which is different from the common cold.
