Foot Pain

helterskelter

Over the course of the past week I've been getting a pain on the top/outside of my left foot. It isn't anywhere near my toes, it's more the mid-upper part of my foot. It isn't swollen and doesn't hurt to touch and seems to triggered by the motion of my heel landing and the rest of the foot rolling forward -kind of at the point where the foot bends if that makes any sense at all!! At the moment I'm icing and rest but I have a marathon in three weeks.... Obviously I don't want to do any proper damage but I'd also like to get my last LSR in at least.

Has anyone had experience of anything similar? If I at least knew what was causing it I'd be a bit happier / more confident about it! I'm going to try to get an appointment with a physio next week but any ideas in the mean time would be welcomed!
