I recently started sleeping with a pillow between my legs and found that my ribs/spine are shifting back [ to where they "should be" ]. The things, is my spine because it curved to the right for so long is now waving a little. IT was not like WOW your spine is bent but....now that it is correcting it is bothering me I might have a wave in my spine. I was wondering can anyone recomend something which will help line my spine? It could just happen on it's own by using the pillow......but I would liek to ENSURE this.
