Hi @drewv and welcome to Connect. I would like to share this link on right middle lobe syndrome: https://www.hopkinsmedicine.org/health/conditions-and-diseases/right-middle-lobe-syndrome

Is this something you have been diagnosed with?

Yes. I have been diagnosed with this. They are recommending that I have my right middle lobe removed (losing 30% of my lung function).

This link is concerning childhood RMLS. I've been diagnosed as an adult. I cannot find anywhere that specializes in adult RMLS.
