question: I have shortness of breath and heaviness in both of my lungs. Recent CAT scan showed fibrotic changes in the small lymph nodes in my lungs. I have been an asthmatic for over 35 years and in the last few months my lungs feel very different. At times, it is difficult to speak without shortness of breath and slight coughing. Not sure if this is related... but my fingers and hands turn blue when I exercise. Any ideas?
