Hello there...

i would also suggest getting your pelvis alignment assessed by a suitably qualified physiotherapist for nutation/counternutation of the sacrum and or innominate (the hemipelvis). alignment abnormalities (as can arise after impact injuries, landing crookedly on the leg or muscle imbalance) can lead to all of the symptoms you describe due to mechanical issues but also muscle overcompensation in attempts to stabilise the pelvis. i would query that you may have an ipsilateral innominate up-slip or rotation but be careful because often innominate rotations can be misdiagnosed as upslip so you need the right treatment. someone who examines this thoroughly and uses muscle energy techniques to establish alignment and who can also provide you with suitable stretching and strengthening for maintenance of alignment would be beneficial... and Check your glute medius and abductor strength to eccentric loading, perhaps have your pelvis assessed before and after a run to see if it's a fatigue/weakness enhanced problem.

i hope that helps
