I recently ran the Dublin marathon, I trained for 5 months and during the last couple of months of training I developed pain in the top sof both feet solely when getting out of bed in the morning, it was more like stiffness, and would soon go away once I got moving. I didn't have any pain when I was running. It's 3 weeks since the marathon, and I still have the foot pain, now it is not only in the morning but also anytime I have my feet elevated ie. lying on the sofa. It's general stiffness and intital pain which then goes away once I am moving, again no pain or soreness during or after runs. I have no idea what this is, and whether I should go and get it checked out? Any ideas or experience with similar?
