Leg imbalance and hip torque
Recently, I've broken into the low 300s for squat and deadlift. Since then I developed a pain/numbness in my left hip. Subsequently, the pain has spread into my lower back/sacrum area.
I went to a sports medicine doctor and she said that a) my left leg is longer than my right and b) this imbalance has caused my hips to torque to the right. This makes sense since my gym partners say that I tend to pivot a bit to the right when I squat.
I've tried orthotics in my shoes (even when lifting) and it helps a bit, but the pain is still there. Disc issues have been ruled out by an MRI.
Has anyone else overcome this type of issue? What kinds of exercies/activities would be good to "right the ship" so to speak? Maybe single leg stuff?
