Determining the underlying cause of lower back pain can be challenging without chiropractic assistance. If your pain is concentrated in a specific area and worsens with movement, it's often muscle-related. Conversely, if the pain is widespread and exacerbated by sitting or standing, it may be disc-related. A bulging or herniated disc can irritate spinal nerves, affecting muscles from the back down to the legs. A prompt examination by a chiropractor can pinpoint the source of pain and prevent additional damage.
