hmm try resetting your pelvis first:
does this cure your leg length discrepancy? if so, then do this before your workout, and then after because probably what you did in the workout will cause it again. you can always test before doing, by laying down and seeing if your legs are the same length. but doing it doesn’t take all that much time.
structures all around the hip could be issue: quads, hip flexors, adductors, glutes, hams, lower back, TFL, etc. these should all be checked via smashing for tender spots. the good ol’ banded hip distraction mobs will be good for you as well. check deep squat and external and internal rotation at the hip also. good luck!
