My 13 year old has had a cough for almost 3 weeks. He has chest congestion and coughs so hard he gets red in the face and ends up almost vomiting. Can coughing that hard be harmful?  Should he see a doctor? I had called in but was told without a cough or wheezing i was probably wasting my time and the cough wouldnjust have to run its course.  Just worried if coughing that hard can cause damage?            Thank you
Thanks for your question on Chat Doctor. I can understand your concern. Yes, you should definitely take him to the pediatrician and get done 1. Clinical examination of respiratory system 2. Chest x-ray. Cough for more than 2 weeks, chest congestion, wheezing etc. are commonly seen with lung infection (pneumonia) and bronchitis. So chest x-ray is needed to rule out infection. He may need higher antibiotic, inhaled bronchodilator and inhaled corticosteroids (ICS) and other supportive Chat Doctor.  So don't wait at home and consult pediatrician. Hope I have solved your query. I will be happy to help you further. Wishing good health to your son. Thanks.
