Sue, thanks for all your info. TriGeek, just wondering if you came up with any further insights after your recent orthopod visit, or have come to any decisions. Would really appreciate keeping in touch, as it sounds like we have exactly the same problem. One of the big mysteries for me is why it hurts sometimes much more than others, without any relation to having walked more or less. Do you find this to be the case? There was a time when it hurt awfully while trying to sleep; now that isn't as big a problem--but maybe because I've cut back on walking?
