What is the most common cause of lower back pain?

Muscle or ligament strain is recognized as the most common cause of lower back pain. This type of strain typically occurs when the muscles or ligaments in the back are stretched or torn, often due to activities that involve lifting heavy objects, sudden awkward movements, or poor posture. These strains can lead to inflammation, muscle spasms, and discomfort, making them a frequent issue for individuals experiencing lower back pain.

Understanding that muscle and ligament strains account for a significant percentage of lower back pain cases is critical for both patients and practitioners. Effective treatment often involves rest, physical therapy, and exercises to strengthen the surrounding muscles, which can help prevent future injuries. Careful attention to body mechanics during activities can also minimize the risk of strains and subsequent back pain.
