Stevie's limp

[dontlookdown]

I've read some reviews that mention Stevie having a limp at one of the recent shows.

Does anyone know what happened?

I think I remember her having knee or hip problems a few years ago. Was wondering if this was the same thing.
She should take a break from the heels, I think...

I've noticed in some recent youtube videos she looks like she's been putting her hand on her back.
Maybe it's back pain/issues.
