Dear Alophysio,

Your information did indeed help - thanks. I asked my physio if my he thought my ligaments were disrupted but he felt in the glide test the right Wikipedia reference-linkSIJ felt "jammed", and weren't loose in true ligament disruption. Also they modified my quad stretches which now no longer hurt

Things have changed a little more - If you can bear it I would love to know your thoughts on a few more questions I have, you seem to very clued up in this area. As an endocrinologist I live up to the stereotype of pouring over the details!

My symptoms now seem to have more or less confined themselves to the right and currently my pelvis is "holding" as my physio puts it ie level and locking, for one week. The problem I have now is right lumbar pain (as opposed to left lumbar /right SIJ as previously) which may be attributed to a tight Q L and psoas. My physio says he is reluctant to release these off incase in creates an imbalance in my pelvis again, but as this area is the main source of my pain I would love something to stop it. Is it possible that once the pelvis becomes stronger with force closure through rehab, this may take off some of the overactivity of these lower back muscles? In which case I need to just be patient with this pain as the stronger the weak muscles become (ie gluts) this should in theory help? Or should we be treating these muscles in spasm as otherwise the gluts etc won't be able to fire properly due to pain inhibition. At the moment these right lower back muscle spasms are worse on sitting and leg lifts (specifically on lowering the left leg is when I feel it in my right back).
I know you can only give your best guess.

Also what are you feelings about direct manipulation of the sacrum for sacral torsion rather than MET /manipulation of the surrounding bones? Some people say it is not necessary as the sacrum can correct itself if the innominate bones are corrected.

Also do you know of any recommendations for experts in London - I will be based there for work for a while.

Thanks!
