I've played through broken fingers and sprained ankles but when those cramps hit, it ain't much you can do.
I saw someone compare Kobe taking FT shots with a torn achilles with Lebron's cramps. I've torn my achilles and it was only painful the moment they snapped and after surgery. It didn't hurt at all right after they snapped and I ended up hobbling pretty far. Cramps are very painful. - Rodfather
