Bronchoscopy- lung biopsy- breathing

I would like to ask anyone that has had this done, how long did it take b4 you you able to breathe correctly again. On 9/11/26 I had a bronchoscopy done as I had a spot show up on my CT and a it also lit up on PET scan, they stated it was deeper in the lung , after the biopsy. However my problems are, they only used 2d and was not able to get a biospy, they state it was just found when , the dr went back for the 2nd time through my files and showed it was there in Jan. , beginning of the year. The tissue, lymphnods, ect around it came back Benign. Its been a wk., CT Sd lung it back operational, oxygen is 97+, but I'm still struggling to breathe. When they were coming back out air escaped and 15% of my lung collapsed. Stayed overnight at hospital. I have breathing treatments and inhaler, but still occasionally gasping for air. How long till I can breathe normal again ? And they want me to drive like 3 hours away to a higher scale hospital to have it done again, I'm literally overwhelmed cause If it collapsed this time, what if there is a second and its worse. Or what it if goes good , they are not leaning towards cancer but need to rule it out. Any experiences please comment as this would help and be greatly appreciated.
