I am curious about how much deep chest and/or upper back pain everyone experiences, and if you notice it increases with an exacerbation? I have it nearly all the time now, but other wise I am relatively asymptomatic. I reported it to my pulmo at Stanford, and she dismissed it. My CT scan in June showed improvement. We are not treating with the big 3, even though now I have NTM abscessus in my lungs in addition to MAC, and all kinds of lovely infections (MRSA, m. Abscessus, acintobacter Baumanii) in my sinuses. How many of you have nagging chest and back pain?
