My 3yr old has just started complaining about her legs cramping. She is a little tall for her age, she is active but these pains come on spuratically. Her right foot turns in slightly and when the pain starts it tends to turn in more. Her pedeatric Dr says it's just growing pains, I think there is more to this. We massage her, put warm compresses on her legs, and give her ibuprophin or tylenol. Is there purhaps something more we can for her.
