Thanks Kar, your description of a spur sounds identical. It is worst when I get up in the morning though, then eases until I try to walk normally.
I'd be grateful if you'd PM the info on the vegetal silica. Best to do it on Friday night by the sounds of it...
I have a form for an X-ray from the doc. My surfing on the net says if it's a metatarsal stress fracture it usually doesn't show up for a few weeks though :-s
I have an appointment with the doctor again on Wednesday but not really sure there's much point until have had the x-ray, which I think I'd rather wait for.
Thanks for the advice Kar, just frustrating when I have no real recollection of anything major happening to cause this much pain! At the time that I think I did it, it really didn't seem like much more than an annoyance.
