I have had rheumatoid arthritis for thirty plus years and I have to say, I feel like every time there is a post like this I am one of the people who answers “yes, me, I have that!” 😂 I have fibrosis in the lungs and the beginnings of ILD, apparently. It is very mild but now they are “watching it.” Believe it or not, and this is going to sound silly, but I sing all the time when I can and actually, that has helped to keep my lung capacity better and bigger. That’s what they told me, anyway, when they asked if I do breathing exercises - I said “yes!” I sing showtunes when I cook. I have no idea if that helps but either way just know, you are not alone. Keep on keepin’ on, DPM
