Hi Christian (Christina?),
Pain is not typical of PDAs. It is probably worth call your cardiologit to let them know about the pain. As an adult cardiologist, we don't see too many PDAs. I do not know if a reason to worry for chest pain and a PDA and a quick literature search didn't turn up any concerns, but I would talk your cardiologist to make sure. Sorry I can't be more helpful, this is not a problem that I am that familiar with.
Good luck
Thank you for this wonderful site!!
