#asktheexpert my son has had bad cold and cough from past one month.. the is 4 and half year old.. he was prescribed solvincold Af and levolin for a week.. then It dint go so we again consulted and doctor gave him ventryl.. but he had no reaction to it... cough became even more worse so doctor put him on novamox 250 ... Now the cough has reduced and cold had gone... but since two days again he has caught cold... why is this recurrent cold happening to him?... That too in summers??
