I can reply to this wearing several 'hats' one of which is as a specialist Consultant Physio, and another as a bod who has injured a disc in the past. My disc was damaged in a ski accident several years ago, healing well, but leaving a tag of tissue. At times when I pivot over the same segment, and cause localised inflammation to arise, I develop an involuntary deviation, or 'Wikipedia reference-linkscoliosis' as my subconscious protects me from pinching the damaged area. Its quite involuntary and bears no relation to un underlying developmental scoliosis. After a couple of days when the iflmmation subsides, so does the deviation /scoliosis.
This pattern is frequent in folk with swollen inflammed deep tissue, our subconscious is protective by nature, and instinctively 'moves' us to a naturally safe pattern. Patterns of posture are habitual and movement is a learned pattern or behaviour. Frequently my clients with irritabel disc problems present with mild postural deviations, and localised acute pain, no leg pain, no neuro signs. Often disc problems as confirmed with Wikipedia reference-linkMRI.
Disc problems are far more common than we credit
