I'm glad it's doing better.

Twice I've had something called pleurisy...very painful especially when breathing. Dr said it's usually a reaction to viral. the lining of lungs in one small or large area gets dried as a result and instead of sliding gently with movement it grates like sandpaper.

only time and ibuprofen is what works...time being key factor. It runs it's course in a few days.

Just another thought for you. Since you're improving it might fit?

Good luck
