Toddler behavior or something else?

Lana

My 2 year old started complaining of leg pain every couple days. For the last 3-4 days. It's been once a day, same leg. She will just say "owie, leg hurts" then continue to run and play like normal. She isn't limping, she hasn't had severe pain just will say some comment, Touch her leg, and that's it. Does anyone else gave have this happen at all before? I'm concerned because I cant tell if shes really in pain or not and Google scares me.
