Hopefully Bushy will chime in here as well.
I’ve been experiencing on and off “one sided (left) back pain” for a couple years now. I actually met with Eric Cressey last year and his recommendations have helped me tremendously. Seems like a healthy dose of foam rolling, specific hip mobility drills and etc was enough to get me deadlifting and squatting relatively pain free.
I still feel some residual pain (not nearly as bad as when I first hurt it), but still bothersome nonetheless. Sometimes when I stand on right leg, I get some back pain on the left side. I know that during a single leg stance, the glute medius and adductors stabilize the one leg, while the Quadratus lumborum prevents the opposite hip from dropping.
Now to me thats a tall tell sign that my QL is at least one culprit in my back pain. My question is, do any of you have any tips of getting to the QL? I own the trigger point book and have tried the thera-cane, ball against the ball (all sizes), but its still hard for me to locate and distinguish the QL from the erector spinae. I’ve been to a couple A.R.T guys but they don’t seem aggressive or even diligent enough in their work.
I found this interesting article and have tried attacking this spot in the QL, but to no avail:
