my child is 4 yrs old he always appears cold (nasal blockage) more or less even after taking medicines so what is permanent solution for this..

A. that's cold. cold signs like running nose , stuffy nose and also fever can occur . Start with indirect steam inhalation for now relief and also start nasal saline spray 4-6 times a day also is safe . For cough , need to check for dry or not . Visit doctor immediately if breathing problem .
