Hello June's Terry,
Thanks for the update. The assessment has found that on certain postures there is an imbalance in the muscles on one side compared to the other. It is not uncommon for this to occur around the pelvis as
the body is trying to stabilise the pelvis due to the symptoms. The pelvis is the centre of gravity of your body and is very sensitive to change. The problem is that the muscle tightening is an indicator of a
problem but is not the actual problem.
If you have a low back, sacro-iliac joint (SIJ), hip or groin pain the muscles (erector spinae & piriformis) around the sacrum can react the same way. If the muscles on one side of the pelvis are overactive trying to splint the SI joint then you may feel hitched and rotated. The muscle reaction is not specific enough for full diagnosis. I had suspected that SIJ area muscles may be contributing
which is why I suggested a support belt to assist in diagnosis. If a support belt stopped the symptoms, including the click, then it is less likely that a labral tear is present. A support belt needs to be applied when you are lying down to have the best effect. Various brands are on te market. We use a Serola, but have used other types. A belt should not be made from stretchable material, be around 50 mm (2 inches) wide, but can have extra elastic side tensioners. If the SI joint is the problem you will need to wear a support belt for at least 6 weeks to allow for settling of the joint. If this proves to be the case feel free to write again and I will add management information regarding belt use and weaning off the belt correctly.

Prognosis is good once a definitive diagnosis is made. I think your physio will need to rule out the sacro-iliac joint as a cause by treating the area and determining your response. The treatment would include
settling the tight muscles, reducing sacro-iliac joint pain (possibly by electrically stimulated dry needling - same needle as used in acupuncture) and stabilising the SI joint via belt usage.
I hope the above will be of further assistance.
Cheers,
