Sarah I can't provide a diagnosis but I have a similar problem, and I've come to the conclusion that it is some sort of inflammation in at least one of the tendons in the foot.
It does come and go, and I am pain free in some footwear (factory work boots) but other footwear (office brogues) make it worse. Taping has helped. Ankle stregthening exercises have helped.
I think we expect soft tissue injuries to heal in a few days or weeks, but in fact they can take months, even years. I think you should do all the things that help, and as few as possible of the things that don't, and hopefully it will improve
