Chronic back pain is defined as persistent pain lasting more than 12 weeks, even after the initial injury or underlying cause has been treated. It commonly affects the lower back and can result from conditions like herniated discs, arthritis, poor posture, or spinal stenosis. Symptoms may include dull aches, sharp pain, or stiffness that limits mobility. Chronic back pain can interfere with daily life and reduce quality of sleep. Treatment options include physical therapy, medications, lifestyle changes, and in severe cases, surgery. Early diagnosis and a personalized care plan are essential for effective, long-term relief from chronic back pain.
