Hi, I’m sorry you’re having trouble with your breathing, I know how frustrating this is after my first lobectomy and a wedge removed from another lung. I’m using Symbicort inhaler and it helps but sometimes I need more especially when it’s warm and humid, it’s hard to breathe in air that’s heavy with moisture. I don’t have an ongoing cough but I do have moments where I can cough a lot and it’s also dry and nonproductive, I would be more concerned if I had a lot of mucus coming out. I think that you should see the doctor to be sure that it’s nothing serious and perhaps a cough medication might be helpful, a dry cough is often due to something irritating your airways and the weather doesn’t help much either but a dehumidifier might be helpful for you, I hope you feel better soon, best wishes.
