Dear Lesliefx:
Have yopu been assesed for pelvic angle difference?
Try this simple test.
Place your fingers on the right and left ASIS. Stand with foot position at 30 cm. Then increase the foot width using hip abduction directly lateral.. As you increase the foot width to 60 cm, then 90 cm note if the one ASIS moves inferior to the other. if you do your problem may be associated with pelvic bone problems or pressure to the bones by a muscular problem.
Once you have done this please contact me.
Best regards,
Neuromuscular
