I had a lot of issues with my IT band back when I did marathon training / endurance sports. Mine stemmed from my quads being significantly more developed than my hamstrings / lower posterior chain. Any imbalance between the front / back of your legs/hips can cause tracking issues, which will then overload your IT band or in the case of walking backwards, your MCL. Also pressure point therapy using a lacrosse ball right into the hip attachment of the IT band was one of the few things that gave me relief. Good luck.
