It was pointed out to me a good few years before any of my back problems began that I had a slight sideways curvature of the spine (Scoliosis ?) and this was again pointed out to me after my slipped disc 5 years ago. I have been told it is now virtually non existent, and my Pilates teacher loves to tell me how it is all her hard work that has achieved this ....
I wish I had had the foresight to have taken some pictures of it then, it would have been interesting to do a comparison now.
I will see if I can get a picture now
