Hi doctor, Last 1 month my son had severe cough. Initially started with fever, later cough continued. WBC was 18000 after 10 days of fever, doctor took xray and said mild infection and cold mucus in lungs. Levllolin, chericof, Nebulizer with asthalin. After some 4 weeks when budecort was added, kid started feeling better and all medicines stopped.. now again severe cough started 3 days before which is non stop now. Whenever he get infection, cough is severe and kid couldn't sleep any day. Kindly advice and suggest any relief medications for cough if advisable or any other solution. Thank you!
