My 9 yr.old daughter has chest pain and difficulty breathing periodicaly, what could be the cause of this?

Asthma?: The most common cause of chest pain and difficulty breathing in a child is asthma. It is especially likely that is is asthma if there are triggers like exercise, cold, and allergens. It is also possible that there is a musculoskeletal issue. If the ribs are not moving freely with the diaphragm it can also cause these symptoms. Both can be treated easily by inhalers or manipulation respectively.

Maybe asthma: The symptoms you describe could be asthma or something more serious. I would recommend that you see her doctor for evaluation as soon as possible.

If she has symptoms : of asthma such as chronic Or recurrent cough (especially at night), wheezing, shortness or breath or exercise intolerance and a family history of asthma, is would be especially important to be evaluated ! Another consideration would be costochondritis, which is inflammation of the connective tissue in the rib cage ( very painful but not dangerous).

Pulmonology : A virtual consultation may be helpful to you and your physician. Pulmonary function testing and evaluation for possible causes including asthma should be considered.
