Jim, I found a more current discussion with members who also have right side diaphragm paralysis. Here’s a link to that discussion group.

Members @giller198 and @lms4ever also share the same condition. Hopefully they’ll be able to offer you some suggestions. It helps to know you’re not alone with these symptoms.

I’m happy to hear you’ll be seeing a pulmonologist next week. It will be comforting to get some answers.
How long have you had the shortness of breath? Were you ill recently?
