Patient: "Doc, it hurts when I do this."

Doctor: "Then don't DO that."

In the Chronic Pain forum, you also mentioned fallen arches (flat feet) and plantar fasciitis. You've got a lot going on there, and a lot more that we don't know (age, weight, medical history, jobs/professions, activities & more) plus the chronology of events that all go into a doctor's diagnosis. You may have some kind of strain, repetitive motion injury, osteoarthritis (degenerative cartilage) or just normal aging stuff as your body gets older. Some of this may be related or it may be coincidental.

Since you're going to an ortho surgeon in the near future, I'd read some articles Googling: first visit orthopedic surgeon and see what s/he's got to say.
