I was in a similar situation with persistent cough, nodules, trees-in-bud, etc. My local pulmonologist went on medical leave and wanted me to wait for bronchoscopy until he returned (10 months after first CT and 5 months from the discussion). I was already on wait list at Penn for second opinion, but lucked into a cancellation at Mayo. Great decision for me. I had a diagnosis and plan in 5 days, including education. I’m now in Penn’s bronchiectasis clinic and am pleased.
I’d encourage seeking subspecialty care from those who specialize in bronchiectasis. Good luck!
