ColdFoot post trauma. Injured foot last night, saw doc, had X-ray, and no broken bones. Sprained, swollen and "freezing" cold. Trauma increases pressure within a muscle compartment and Imost often due to injury. It causes bleeding in muscle, which then causes increased pressure in the muscle. This pressure increase can cause nerve damage due to decreased blood supply. Ask about compartment syndrome. Go see your doc-
