Hi
I've been to see Nick Syrett at Doctorcall Manchester on St Anne's Square a few times. Nick is a runner himself - Chorlton Runners I think? I've a pin in my ankle from a fractured talus which has affected my glutes.
He assessed me by watching me try (and wobble through) some balancing exercises then watched/filmed me on a treadmill to monitor my style before giving me some follow up exercises to do. He's a physio so could offer this too.

Best of luck getting it sorted!
