Hi @collage ,
I do have all the same issues, plus a few more. Mine is more post nasal drip than congestion. My hiatal hernia is small but it still causes me problems and GERD. I have a lot of nausea & some stomach pain and a VERY limited diet because of it. The GERD contributed to (or caused, they don't know) my lung nodules which are bronchiectasis. I also have an NTM (nontuberculosis mycobacterial) infection in my lungs because of the bronchiectasis. It sounds like you are doing all the right things to control it before you scope. Has anyone told you what your lung nodules are? Good luck with your tests!
