Claire,
Having worked on a number of people with scoliosis I am constantly amazed at how well the body adapts to changes that either come on gradually or that we were born with. It sounds to me like you are doing all the right things to keep your spine strong and supple. Energetically, what I have noticed when working on people with scoliosis is that they sometimes get energy blocks at two key areas: 1) where the curve starts and ends and 2) at the apex of the curve of the scoliosis. Here's what I would suggest to see if you have the blocks: When doing the sitting meditation where you are circulating the Chi around the micro-cosmic orbit (up the back and down the front) get a sense of whether your energy flows freely through your curve. If it does - super you're doing well. If you get a stuck, blocked or twingy feeling then the area is being restricted energetically. Breath into the area and spend extra time focusing energy into it while breathing in and out of it when breathing out - you may notice some heat in the area or some discomfort or tingling - those are all signs that the energy is opening up.
You also mentioned that your curvature was a source of self-consciousness when you were younger - if there is an energy blockage in your spine and it frees tself up you may notice that there is an emotional component to it that may reactivate some of these old feelings you had when you were younger. As I'm sure you're aware that's super as it means that you are healing at a very deep level. Just thank your body for the emotions and the release, experience the feeling and then let it go with sincere appreciation and love for the gift that it presented to you.
Hope this helps,
Peter D
