I've suffered ITBS also and as a runner I can sympathise. I've been self-treating with deep tissue massage, foam roller, strengthening glute med, Ab, Ad, VMO and ITB stretching (this made it more painful at the knee even when I wasn't running). I have seen a physio colleague for acupuncture and another podiatrist colleague for prescription orthotics. NONE of that helped!

The only thing that's helped is changing my running style. I researched Dr Romanov's POSE method (google it) and since running this way I've had no ITBS problems. I'm now up to 40mins pain-free running, all be it after a slow build up. I adapted easily to Pose however I'm trained in biomechanics; it can require perseverance.

ITBS is so multifactorial - you need to address the friction point to start with though. If there's pain there, stop. Then look at the mechanics side of things, gait etc. As Alophysio said, strong muscles doesn't necessarily equate to correct function. Screening for Lx, Wikipedia reference-linkSIJ and hip rotators - assuming your physio's done this. Find the cause then you can treat it - easier said than done though...
