Pain In The Right Leg While In Bed When My 3 Yr Old Daughter Couldn't Get To Sleep,she Willalways Complain Of Leg Pain.Is It Psychological?

When my 3 yr old daughter couldn't get to sleep,she willalways complain of leg pain.Is it psychological? - pain in the right leg while in bed

When I try to sleep with her, always complaining that the pain in the legs (but never at the same place). I'll let you out of bed and play with him until he tired and fall asleep.But she never said anything about pain, while playing.I suspect, she feels no pain, but he wants to get out of bed. What can I do?
