The Psoas muscles impact our pelvis. when our pelvis is tilted our hip is also shifted in an upward direction. This is the biomechanics of the Pelvis.
When the hip is elevated our leg shortens.
So having the Pelvic area well balanced with respect to the Sacroiliac joints which are the large joints of the pelvis is vital.
Walking around on a short leg is compromising the pelvis, the back, the hips and the Bursa of the hip.
So this is like driving a car with bad alignment. Yes you can change the tyres but the alignment remains distorted.
So you can treat the symptom: the Bursa the Back and the Hip but without treating the cause it will return
