Can poor posture cause back pain?

Yes, poor posture can cause back pain. It leads to muscle strain, joint pressure, and disc issues, contributing significantly to back discomfort. Poor posture, such as prolonged sitting or hunching, strains the back, core, and abdominal muscles, reducing blood supply and causing pain. This strain can lead to stiffness, weakness, and stress on muscles, tissues, joints, and discs in the spine, potentially causing long-term damage if not corrected.
