Just one thought: I can't imagine a boot, even one designed to hold an ankle as giant as hers, would be useful at all. I'm not a bariatric med fag but I do have way too much experience with ankle boots for injuries and one on her would just be squeezing the fluid from her swollen leg and nothing for the ankle.
Imagine that smell...you have to provide some stability, which means tight straps. Her leg is a balloon. *Pop*
Or maybe I'm wrong.
Amber probably stubbed her toe, decided Jade was spending far too much time having a family that loves her and made her mind up to have a crisis. And to someone as dumb/immobile as her, torn toe ligaments is an exotic crisis.
