@kathyjjb I have one that was given to me in a previous hospitalization in Dec 23 which was when my PH was found. My SOB at that time was attributed to that. I suspect the MAC was partly to blame as well. But not suspected to have returned. It’s so confusing when a person has more than one disease with same symptoms. This time I tqhink the MAC came to mind when my white blood cells were elevated and I had no fever and I was having a flare with extremely SOB. My chest x-ray showed a pneumonia that was later believed to be MAC and sputum culture had had an early response. I’ve not heard from the delayed result yet. Dr. appt Wednesday.
