I can't recommend a full course of stretches and rehab Lazyjones, but one stretch I tend to do is to lie on my back, legs out straight and toes pointing upwards... then raise left leg over to the right with toes pointing right, take it until you can feel comfortable resistance in the ITB, hold for a bit, then repeat lifting the right leg over to the left. Does the trick for me!
My apologies if the description isn't very accurate
