I get muscle tightness in my left glute almost as soon as i start a running session, and after the run, it kind of migrates to the IT band. The day after, the soreness emanates from near the ball joint. After some rolling with massage stick, it goes away after two days or so. All the while, it does not seem to be aggravated by my cycling, even when i bike the day after i run. I've had occasional issues with IT Band when bike racing, but nothing this troubling.
Would like to know if the leg length difference (right side shorter) might contribute to this. Also would like to know other than rolling, what other things i could do; should i stretch before the run after warming up? I do a core routine once a week and can usually hold planks on each side for more than a minute, perhaps that's something i should focus on more often? A few threads i read through seem to indicate that this is a relatively common issue that may persist for a few months, and i'd like to know if there are any additional methods that may reduce the likeliness of the flare up.
Many thanks in advance
