My right foot has a dull ache that is present in the centre of the foot / arch towards the inside edge. The area that aches is approximately 40mm diameter. This ache is not present at the start of the day but becomes noticeable after a short 15min walk from the train station to work (I have a short cycle ride to the train station from my house and this does not seem to agitate this). I walk to work in my Brooks running shoes (which are of a design to give arch support. I have been buying this design for 5years, and the current pair are less than 6months old / less than 300miles) and change these shoes at work to an ordinary pair of shoes. My work involves sitting at a PC (ah! Modern life!) and after a while, the ache disappears and I no longer notice it. It will be present again on the return commute home (in running shoes).
The real issue is when I try run. After 5mins running the pain will be enough for me to have to stop. Which is quite inconvenient for the marathon training I need to do L I have been running for quite a few years now and never had this sort of injury before. I think the pain may have started after a long practice run in old trainers and been exaggerated by a recent half marathon run in wet muddy slippy conditions with my new trainers.
Any advice to get me back on track please?
