Well, got in to see the physio today. He doesn’t believe in stretching unless something is tight. Anyway, there is some tightness in my glutes but the IT band is fine.
Seems it might not be my IT band after all. It could be the peroneal nerve passing through various insertions at the head of the fibula. He has recommended that I “floss” the nerve and shown me a couple of exercises but told me to keep going with the core and hip abductor stuff that I started doing when I thought it was ITBS.
Thanks for all the comments. If they prove one thing, it’s that no one seems to have the definitive answer about IT bands.
