I thought I would report that lately the spinal nerve and sushumna (central channel) has moved from being in front of the spinal column (down the center of the body) to being where we originally started tracing it, along the spinal column. This ‘moving back’ to align with the spinal column seems to be linked to the fact that back channel which is now open and smooth, creating this re-centering of the central channel.
I don’t know if this is helpful to anyone - I am just reporting an observation.
