My right foot hurts like on the inside, the side by my big toe. It hurts when I walk, stretch, and rotate my foot. At first it was a minor pain, but now it really hurts. I tried to stop walking on that side and developed a pain on the left side of my calf. Please can anyone tell me what I can do it really hurts and is starting to cause me problems in walking. I am 16 by the way.
