elliptical

I did four miles on the elliptical to give my foot more of a break yesterday. I did high resistance and was going at a pretty decent pace. My foot still hurts but the degree of pain fluctuates. I don't even know if the elliptical was better for it or not. I'm still not sure if it is a stress fracture in the making or if it is a pulled tendon. I have been icing it but the icing doesn't actually make it feel any better. It never hurts so bad that I NEED to stop running or walking but just enough to make me concerned.
