erika, I'm so sorry for your loss.
The pulmonologist thinks that, given his whole clinical picture, Tim's abnormal test results are within an acceptable +/- range. Which is to say, he thinks everything is JUST FINE!!!!!!!!!!!!
He explained what the abnormal results *could* mean, from a disease standpoint, but he said that right now he doesn't think that's the case with Tim. He wants Tim to repeat the tests in 1 year, since RA patients can develop lung issues. This way, he said, they can stay on top of it.
THANK YOU guys so much for your prayers and good thoughts and for listening to me when I've been losing my damn mind. I love you guys.
