Cramps

Something inside you contracts — suddenly, uncontrollably, with a force that surprises you. A muscle hardens into a knot. An area of your body that was soft and mobile just a moment ago turns to stone. You want to loosen it, but it won't obey. You want to keep breathing, to stretch, to move — but your body has for a moment removed itself from your control.

A cramp is exactly that: a moment in which your body acts against your will. Something contracts and can no longer let go. No impulse from your consciousness reaches this muscle anymore. It holds. It clings. It refuses to open.
