Does anyone have any techniques to mobilise a segment of chronically stiff spine? I have a small t8-t9 protrusion. I have narrowed all my pain down to muscle and joint pain rather than any disc pain. The issue I have is after periods of inactivity (especially sleeping) my spine is stiff as a board (only t12-t4 approximately), this in turn leads to overuse of muscles and muscle pain. If I could find some useful mobilisation techniques I think I could be pain free again. Any ideas?
