Nice to meet a kindred. I found out about my MAI in a very similar way last year. I had a syncope episode, out of the blue, where I hit myself hard in the back. The pain was so bad that I thought I cracked a rib! I went to see my PCP and she ordered an x-ray which showed bronchiectasis and a mycobacterial infection. Then the CT scan confirmed this. I felt really lucky to find out early. I felt it was my body asking for help, hence the syncope.
