Some people with RA, especially men who smoke or used to smoke, are more likely to get serious lung problems.
When RA inflammation causes scar tissue to form in your lungs, you might notice chronic cough, shortness of breath, fatigue, and weakness.
RA may inflame the tissue that lines your lungs. That can lead to shortness of breath or pain or discomfort when you breathe.
See your doctor right away if you have unusual breathing problems or a cough that won’t go away.
