I've acquired a bump or lump under my foot . It's in the inside edge of my right foot a bit below where you'd play the ball when passing a football with the inside of the foot. I suspect it's an over-use type reaction to walking 30miles in two sessions at weekend and generally increasing mileage over last couple of months. Has anyone seen or had a similar problem? I've been icing it and am away next week so won't be running for a week or so.
