I'm having trouble with my left foot. I walk a lot in my job, but the pain at the top of my foot and the side is really bad, as though I have broken a small bone. What should I do?
A number of things could cause this. You could have a stress fracture in one of bones of the top of the foot. Oddly enough, flattened arches can also cause pain in the top of foot by compressing the bones there. If that's the case then an orthotic could do the trick for you but you'll have to see a doctor to diagnose you.
Be aware that many times pain in the foot is caused by shoes that don't provide proper support or that don't give your feet/toes enough room to move. A podiatrist could diagnose your problem and help you out with proper footware. Good luck!
