Thanks Lynn, I'm glad to say that a lay off over christmas (with plenty of turkey and pudding) seem to have done the trick. I'm only just catching up with my training as I also suffered a cold!! It can be so frustrating when all you want to do is run and a seemingly tiny problem can prevent you from doing so.
I think I may be suffering with a similar problem. I am well into a training schedule and have just increased my weekly mileage to approx 30. The last couple of runs ended with a local pain on the top of my foot adjacent to my big toe. I treated it with ice and brufen then ran a couple of days later, the same happened. Having given my foot another couple of days rest and ice, I ran a short distance only to find the onset of pain sooner and more severe. I have decided to give myself a couple of weeks off to see if I can clear it!? Any thoughts?
