I am much older than your daughter but I do have similar pain when I run. My trainer does a lot of one legged strength training with me and it has helped tremendously. Also, running some training runs on trails helps too-I find the varied terrain a relief to my lower legs and it also makes your lower legs stronger. I would take her to a chiropractor-it can help open up her hips. She also needs to have a good stretching routine for those IT bands.
Don't know if any of that helps?
