Really sorry to hear you are having a rough time.
I had a lobectomy in 1963 - things were very different then and so I can't really comment on the amount of pain you are getting, except to say I hope they get this sorted out for you soon.
If I understand correctly you are concerned, naturally, about how the bronchiectasis will effect you and what lies ahead. It will take some effort from yourself and your medical team to keep on top of things, but if it helps to know I have had bronchiectasis for 64 years from the age of 5 months old.
Not sure if your consultant is still on the surgical side or not. If brociectasis is confirmed you really need to be under a respiratory consultant who has a special interest in cystic fibrosis/bronchiectasis.
The most important thing you can do for yourself is mucus clearance - your cons should refer you to a respiratory physio if they have not done so already. Pysio will teach you various methods and gadgets and you can then decide which method you prefer which works well for you. It has to be done every day to stop the gunk from pooling in your lungs and getting infected. On the one hand it's a pain to do, but on the other hand it gives you some control over your own health.
You should also be given a medicaton regime. Most bronchiectatics have a supply of antibiotics at home and it is also a good idea, if possible, to get a sample down to gps before you commence with your abs. One reason is if the bugs in your lungs are not sensitive to the abs you are taking, by then your gp should have the results back and can then give you an antibiotic which the bugs are sensitive to. Also it gives a pattern to you, your gp and your consultant what bugs like to take a holiday in your lungs.
A lot to take in and not easy if you are in pain, but you will soon get used to managing your bronchiectasis.
Good luck Darryl
