Hi thanks for asking question. You mostly might have viral flu like respiratory illness... Symptomatic treatment done for it.. If still cough is wet then expectorent syrup containing ambroxol can be taken.. Steam inhalation also useful... If still condition worsen chest x ray done for rule out bronchitis or pneumonia like condition... If need antibiotic given... Drink more water. For few days irritant to respi tract avoided like excess spicy food, smoking ... Hope your concern solved. Take care...
