I can so appreciate your situation. I have Stage IV COPD, but I think I am a tad more comfortable ....Have you talked to your Pulmonologist about adding a steroid to your inhaler treatment. I am on Breztri which is a combination of three different types of medication for COPD management. Also in 11/23 I had Zephyr valves inserted in my left lower lung which improved my breathing and ability to do things by 90%. Dupixent is a new medication by Regeneron that greatly helps with the secretions.....have been on that for 6 months. A real life saver. These are things that I would definitely address with your physician to help improve the quality of life! Wishing you the best!
