Without a specific diagnosis, you might have some problems with any therapist.
That said, I know from running that many if not most cases of ITB syndrome are related to core muscle weakness and lack of stability in the hips and core. Strengthening the entire core (abs, obliques, lower back, glutes, gluteus medius, hip flexors, quads, hamstrings, spinal erectors) are key to providing this stability. Even though it may seem like a lot of different muscles, you can train the core through just a few different compound (multi-joint, total-body) exercises.
Just keep in mind that strength exercises work best as prevention. They won’t fix pre-existing injuries. But sometimes, the strengthening and muscle balance you get from strength/core training resolves muscle imbalances, and then you find that you just had muscle imbalances instead of injuries.
