My 2 1/2 year old grand daughter has had chronic leg pain for a few months now. Its the same leg, same area, and its always at night. She creams with pain and the tears break my heart for her to be in pain and I don't know what to do. There is no apparent bruising that is visible, no falls or any thing of that nature. Is this something to worry about or am I just over reacting.... I have raised five children and I have no memory's of my children having growing pains of this nature if that's what this is.
