BTW, remember that toe question from December?

[hmpf]

That toe still hurts. The pain's kind of burning, though only fairly mild by now, and not very localised. I had an x-ray done in December that showed nothing wrong. Any ideas what could cause five or so months of intermittent pain of varying severity and not leave any trace visible on an x-ray? I feel kind of silly seeing a doctor about it *again*, so I haven't done so yet, but the pain's mildly annoying, and not knowing what it means is even more annoying.
