I was diagnosed with Type A influenza with bronchial thickening, is this anything to be worried about?

Hello…I am a 50 year old female. I was diagnosed with Type A influenza three weeks ago, on December 24, 2017. I continued to have the regular flu symptoms for several weeks and was experiencing quite a bit of coughing and some chest pain. I went to an urgent care center on January 9, 2018 to follow up, at which time they completed a two view chest X-ray, and I am attaching a copy of the results. The doctor indicated that I did not have pneumonia, but prescribed azithromycin to be safe, which has helped. He said I may have had bronchitis. I just saw the chest X-ray results today and see that it mentions “bronchial thickening” which made me concerned (I suffer from health anxiety). Is this anything to be worried about? I did have a CT scan and ventilation perfusion (?) scan of my lungs back in 2005, which showed mild bronchiectasis in both lungs. I have never smoked, am in good health and have never had shortness of breath, etc. Thank you for your assistance!
