I went though a nasty IT band issue in 2019 lasting from end of March to start of August. Usually never one thing on the ‘why i’m injured’ list, but I think the majority of the pie chart was unstable footwear & conditions. IE Yak Tracks on snowy paths & Nike 4% shoes. The shoes didn’t work for me. On the road to getting healthy, I spent a lot of time in PT, got orthodics, & ran in stable shoes ==> Clifton, DS Trainers, & Tri Noosas (RIP; Great shoe).
Also, I got this & things kind of cleared up around the same time (not the solution, but helped). https://www.amazon.com/Pro-Tec-Athletics-Band-Compression-Wrap/dp/B005B00J5K
