No doubt anxiety and stress is what has kept this flare going. I went to TX to see a foot specialist about other issues besies PN. Very stressful, expensive and so far not helping. At least one more visit to go.

I haven't found any meds that are helpful, but I may try a massage after I get back from this next trip. Acupunture seems to help, but my lady is on vacation.

I agree that the cabin pressure and oxygen levels would make sense and the anxiety is likely prolonging the episode.
