@amn17 Hi. When was your resection surgery? Yeah, I bet it does hurt like heck to cough. As for the saline most of us on here use, it is either 3% or 7%. It has to be prescribed by a dr. Your dr may not want you doing it yet as it could really irritate your healing lung. That is a discussion you may want to consider with him/her. I hope that you get to feeling better soon. Did you have the surgery at NJH?
