I had one bad round with IT band issues a year and a half ago. I think mine was increased due to a prior broken femur - I don't think they ever get those put back together exactly straight.
Anyway, I went to a chiro/sports therapist. He did acupuncture and hooked mild electric current to the needles while inserted. Then he did shockwave treatment. This was the first time I'd ever been to such a doctor & thought the procedures were that of a witch doctor at first. However, he fixed my issue.
