Welcome fellow sojourner to our strange new world!
You are not alone in the information overload of this new diagnosis.
Getting on track with your personal regime is paramount.
To do that, I would suggest you put this question to your specialist, or member of your medical team.
There are ways to help in your coughing and clearance routine; such as nebulizer, or saline, and especially getting instruction on 'how to cough'. With good instruction, you will soon be an expert yourself.. it is all do-able!
I had great improvement when I switched to my nebulizer.
The best suggestion for someone who is just 'beginning', is to ask your doctors these very important questions. They would be pleased to direct you to personel ( maybe physio), or videos ( they will have suggestions), or equipment, medications, etc that you will find helpful. It would be the start of forming your relationship with your 'medical crew'.
Please don't give up! These are important issues to get understood, right from the beginning!
Let us know how you get on.
All the best!
