question: my daughter has seen a lung doctor for almost a year he has done many test why she is experiencing shortness of breath not only with exercise but at rest as well, she also experience a rapid heart rate, which she see s a heart doctor for that. The heart doc. put her on verapamil and flouricordisone so she can absorb sodium due to her low sodium levels. Her lung doctor does know she has inflamed airway, she was put on many different inhalers, none of them worked, the test from her broncolscopy are coming back as normal we are stuck on what to do next
