Insomnia

Seems I've developed some major insomnia.  My legs won't settle down to go to sleep.  It seems to be mostly my left hip and leg.  I get comfortable for a few minutes and I have an irresistable urge to move my left leg.  I try to fight this urge, but the more I fight the worse it gets.  I'm not sure what I'm going to do about it.  I suppose I'll ask the doctor.  It seems almost disconnected to the surgery, but I didn't have the problem until after the surgery.  The further out from the surgery I've gotten the worse it has gotten.  If anyone knows anything to help it let me know.  I could use any advice about it.
