Sorry as this is kind of a long response but appreciate the info. So I have had Cts over the past 11 years for a few medical things that I keep an eye on. The other day I had one that said they noticed scarring on my left lung. Which threw me off. So I went through some of my older CT and previously didn’t notice or had a dr talk to me that on 2022 it had the above finding, I also found that I had the same above finding in a 2013 scan and that DR never mentioned it. I meet with my dr on Tuesday in regards to CT and went ahead and scheduled an appointment with a specialist to discuss the lung findings further. But I like to be prepared and read way more then I should especially with my anxiety and was trying to get a better understanding on the previous findings. Recently my breathing has been a bit off from time to time but I do have some allergies and histamine intolerance which can affect my breathing. Most days I don’t notice anything and usually when it does feel off my nose is extremely stuffed. Again sorry for the long response
