That’s interesting and goes with what my mother had said. She had a car accident long ago and smashed her knee and the bruising migrated to the ankle/foot. It was just startling to me to wake up one morning after I thought everything was healing and find all this bruising around my ankle. Never got much bruising on the calf. Just a red mark about the size of a quarter that was very tender, so I figured that was where the tear happened.
It is scary the first time it happens!
