A sacralization of L5 means that the L5 vertebra has taken on characteristics of the sacrum. The transverse processes of L5 which normally are small are enlarged with the sacralization condition and attach or articulate to the sacrum.
This articulation generally isolates the L5-S1 segment from motion and therefore back pain will not occur from the L5-S1 segment. Your back pain is most likely from another source than the L5-S1 segment.
It is always normally OK to commence with physical therapy for lower back pain relief.
