Re: doctors don't know why my child has a chronic dry cough
your child's cough can be caused by many things. one being asthma, it is a fact that asthma does not always produce wheezing, it can produce just a dry cough, this is called CVA (cough variant asthma). i understand that the cough is a dry cough, which would also arise suspicions of croup, or gerd, or post nasal drip. this can also be habit cough, does your child cough at night? have you gotten her tested for asthma?
have her seen by an ent and make sure he scopes her, very high possibility of her having gerd, which can easily be treated. a cough is not so easy to diagnose but with the proper doctors and proper tests your child can be on the way to living cough free.
