When I walk outside with varying degrees of incline/decline (not on tradmill), afterwords I am unable to bend my foot up towards my shin. The tendon/muscle just starts shaking and I stop because it feels so odd. It doesn't necessarily hurt. If I hold my foot and force it up there, the muscle/tendon going from my shin area to the top of my foot spasms horribly. It subsides after a few hours.
I know this probably isn't serious, but I'm just wondering the cause. I'd like to make sure there is no underlying neurological problems I should have looked at.
I posted here because I don't like running to the docs everytime I wonder about something.
