As it turns out, the reason she had been experiencing sharp pain while she was walking was because a cyst was developing in her left knee. She can only conclude that the cyst burst during ceramics, leading to immediate swelling and the complete inability to walk.
As a result of the cyst giving up on cyst-dom, Abiona's left leg is quite swollen and her knee is very bruised. This is, however, a situation which should resolve itself.
She has not regained full speed quite yet, but is thrilled that she no longer has to don the "immobilizer."
