My 3yo dd has been complaining about having a "dizzy leg".
My first thought was that maybe she's got 'pins and needles' in her leg, but it didn't go away and she was still complaining that her leg was "dizzy" some 3 hours later.
She's limping and can't run - in fact, when she runs, her leg gives out and she falls.
She has showed me where it's "dizzy" and it's just behind her left knee.
It isn't sore. It doesn't hurt to touch or when she walks, but she's definitely limping.
She isn't distressed by it, if fact, she's amused by it. When she falls she laughs 
I'm really confused. Any ideas?
Obviously it goes without saying that I'll take her to get it checked out if it doesn't improve
