Bad posture-related chest pain is a musculoskeletal condition where poor spinal alignment creates muscle tension, restricted breathing mechanics, and nerve irritation in the chest and rib cage.
Bad posture is a pattern of spinal misalignment where muscles, joints, and ligaments are consistently loaded in ways they were not designed to sustain.
Rounded shoulders are a postural imbalance where the shoulder blades shift forward and outward from their neutral position, causing the chest to cave inward and the upper back to round - driven by tightness in the anterior shoulder structures and weakness in the posterior scapular stabilisers.
