I have a bit of it myself after thirty plus years of RA and I know many others with RA who suffer some sort of lung involvement, not to mention all the other co-morbidities that come along with decades of chronic illness. My Rheumatologist just said to watch it for now, and keep an eye on things. Let us know if there’s anything we can do to help, and remember - you are not alone! Keep on keepin’ on, DPM
