My daughter 3 years old, she is coughing during the whole day. Worse dry cough ever. No time gap between her coughing. But when she is asleep. She is hardly coughing. Doctor gave her antibiotic moxclav ds, cough syrup, inhaler asthalin budecort. Nothing is working. What can cause this? Is her problem really that serious? Doctor is asking us to be patient. But we r worried like we will be collapsed any time.
