Any chance you could post a video of you doing a handful of air squats from the front and side? I’m just curious about how you’re moving in general.

I don’t mean to downplay your issue in any way, I’ve just found that often treatments are given to relieve symptoms like yours without much being done to address the cause. If your problem is being caused by some poor general movement habits (that are being magnified greatly if you’re training hard), it will take a more complete approach than mobility work in general to set things right in the long term. This is why Starrett prioritizes fixing motor control issues before mobilizing.
