When I had bronchiectasis flare up ( sinus infection , more sputum from lungs and more cough than normal) I was also given steroid - 5 days of prednisone, but no antibiotics. I also had an X-ray which did not show changes other than what I have. This all was given by an an call pulmonologist ( of course I got sick on the weekend) and confirmed by my pulmonologist. Well I thought I should be given an antibiotic. Yes I got better in about a week but I am still not sure it was enough. Next weeek I am going to NJH and planning to discuss it with dr so after that I will share on this forum.
