thnx for replyin.. well she does feel comfortable in prone.. SLR is negative.. PSIS and ASIS appear symmetrical WRT each other. sacroiliac compression produces pain.. she can feed the baby normally.. i hav advised her not to do cross leg sitting or abduct her legs.. n she finds some relief by doing this. there is no diurnal variation.. i have advised her for an X-ray, she is yet to get it done..i have also advised her mild self mobilisation techniques for Wikipedia reference-linksacroiliac joint which she says has helped her a bit.. hope u can guide me with this information.. thank u..
