Back pain is the most
common soft tissue
complaint pregnant
women generally
encounter. There are a
number of reasons for
this, including:

      Release of the
hormone relaxing
causes muscle
and
ligament                 
 
relaxation, which allows
joints to easily misalign.

      Increase in
weight gain and
forward weight
bearing and
increased
stress on spinal and
pelvic ligaments.

       Poor body
mechanics and
postural habits.

       Rib cage
enlargement
increasing rib
subluxation.

       As the baby
grows, the lumbar
curve and thoracic
becomes
more exaggerated.  
Therefore pressure is
placed on the joints
in the spine.  It may also
put pressure on nerves,
causing pain.
The sciatic nerve, which
runs down from the lower
spine down to       
the legs, can get irritated
causing pain in your
legs.
