For the past couple weeks I have had a pain on the left side of my left foot. It is sore even if I am not standing on it. I have always had pain across my toes but now it hurts on the whole side of my foot. I already went to a pediatris and have orthotics. Does anyone know what this pain could be caused from? I never sprained or injured it in anyway. I do not jog and it became sore while on holidays just out of the blue.
