I have had two docs tell me my lungs sound clear and that if I had ILD There would be a crackly/crunchy sound. I know that lung diseases are hard to diagnose. Pulmonologist has me now taking 1000 mg daily of micophenolate plus singular and zyrtec. It has made my trachea much clearer and less phlegm in the throat. I still drop to 85-87 with exertion so thats the same. I am experiencing some unsteadiness. My question: should I ask the pulmonologist if there is another possibility for the SOB?
