My three boys and I all have asthma. And I just got over pneumonia and my chest also "crackled."
I agree with the others; you...
*Need a second opinion with another doctor (preferably an asthma/allergy doctor)
*Will probably be given a chest X-ray
*Do need to take a parent with you
I know some people "out-grow" their asthma. Better safe than sorry, tho. Please post again and let us know how you are!
