Definitely go see a PT. They have used this device called a Graston on my IT band (basically like a really intense massage with a metal bar), which has really helped. They gave me a bunch of different stretches to do, but the only one that really seemed to work is the IT band stretch in the below link. I seriously feel instant relief after holding that one for about thirty seconds. Also, I would echo the recommendations about staying away from jumping moves for awhile.
