Good luck getting it sorted out. I've heard knowledgeable hyperbaric medicine people say that PFO is only an issue if you are diving profiles where significant bubbling occurs -- so normally a PFO wouldn't be an issue in a shallow dive setting. I was therefore surprised by the PFO story featured on deeperblue.net recently, because the author felt that she was having chronic low-grade DCI symptoms from shallow dives due to her PFO. I plan to take a workshop in advanced decompression physiology in a few weeks, and look forward to learning more on the topic.
