@lasirvent , I have the same condition, but it isn’t neurogenic as far as I’m aware. Six months ago I had a left lower lobectomy to address a small malignant lesion. Stage 1, nodes and margins clean. So “all” I had to do was recover from the surgery.

After six months I am left with persistent left side rib and diaphragm tightness. Deep breaths are painful and difficult.

I also have RA and there is some question as to whether RA is playing a role In the pain.

For reasons unrelated to surgical issues, I went on a course of low dose prednisone. And by day 2, all my rib pain and tightness disappeared - not improved - gone. Sadly, as I stepped down the dosage, the Benefit stepped down as well.

But whatever caused it, it seems to be inflammation. That knowledge is worth something.

I’m not sure that is remotely useful to you but maybe it’s a new discussion with your doc.

We are all unique and have unique drug reactions and side effects. So I caution that my experience is likely not universal, but I felt it worth sharing.
