hi brian, they dont work for everyone, when i had itbs (I had it in both legs at one point) i tried everything, foam roller, band, stretcing excercises, physio etc nothing worked. You need to make sure you are in the right shoes and then what worked for me was just a few weeks rest and then a very gradual reintroduction to running, adding on a mile per week. Its a very frustrating injury, i ran a marathon in absolute agony with it, but it is beatable, everyone seems to be differnet.
I guarantee someone else will be along soon to offer a different solution and many different websites will tell you many diffeerent things, but stick at it and you will find the right solution for you.
