You guys are amazing! Thanks for making a discouraging situation a bit brighter!
I've made a list of your recommendations to explore. It's clear that solving these issues requires a bit of experimentation. I have horrid insurance, so I'm keeping a symptom diary and writing down any self-care I try. That way, if things don't settle down in a few weeks, I might be able to same some time and money in the diagnostic process.
I've been using rolling (Jill MIller's method), yoga, PT based stretches/releases for the hip, foot and psoas, and strengthening the abductors/adductors.
Angie: Thanks for the inspiration! I do at least find the Dansko's fun, and your photos (and yours, too, Krishnidoux) make me a bit excited to give them a whirl.
I'm hoping that, which some healing and attention to stretching/strengthening and biomechanics, I can go back to wearing many of my favorite shoes when I'm not on my feet a lot. I've been pretty reasonable with heel heights in my recent purchases, so I'm optimistic. I suspect I'll always have to be vigilant, and, even in the best case scenario, know what shoes to wear when my feet get grouchy.
