Sacroiliac joint (SIJ) pain can occur if the SIJ is not as stable as it should be; if it is ‘unlocking’. Could a contributing factor be that your sacrum is stuck in counternutation? If so, what might be driving that?
It is important to identify the drivers so that once a correction is made, a strategy is put in place to maintain the change.
A good therapist should encourage, educate and empower you. They won’t ‘fix’ you – it is a partnership!
