How Poor Posture Causes Back and Neck Pain

You may not feel any ill-effects after sitting with poor posture for a few hours, but over time the stress that poor posture places on your spine can lead to anatomical changes in your spine. This in turn can provoke back pain through the constriction of your blood vessels and nerves. In addition, the stress from poor posture can lead to back pain by causing problems with your muscles, discs, and joints.
