Hi CM671, and thanks for your comment. We hear you! In fact, others in the community have shared similar experiences with a runny and/or stuffy nose that posed challenges for their normal breathing patterns. You are definitely not alone!
While I'm hopeful others in the community will chime in by sharing their own personal experiences, I thought you might gain some additional insight from this article which focuses on COPD and runny noses: https://copd.net/living/stuffy-noses. i do hope you find it to be helpful in a practical way.
Wishing you well,
Leon (site moderator COPD.net)
