There's a reason for your ITB problems. Seek out the reason and correct it. Injuries don't just happen, there's always a reason.
Once the reason is found and you get back to running, start all over again. Begin with a very short run/jog and build from there. Within a month or so you can built do a sensible distance and take if from there. At the first sign of symptoms, stop at once and end the run. Don't ever run through it or finish off a run. Stop on the stop and stretch.
My ITB problems were a combination of always running on the same side of the road (the leg on the lower side of the camber became affected) and bad running shoes. Now I have new shoes and run up one side of the road and back down the same side to equal out the effects of the camber I'm much better. I found running down hill was a big problem while up hill actually eased the symptoms. So while it was bad I used the cross trainer (Nordic Skier) machine in the gym followed by a short up hill run on the tread mill. This maintained the majority of my run fitness and actually improved my hip flexor strength which probably helped with the ITB problems. I try to use the Nordic Skier a couple of times a month to continue with the hip flexor improvements.
Good luck.
