Chronic Lower Back Pain (CLBP) is pain that persists for 12 weeks or longer, even after an initial injury or underlying cause of acute low back pain. Low back pain is very common, and at one point, everyone must have faced this problem. Lower back pain that is long-term (for more than 3 months) is called CLBP. This condition might originate from an injury, disease, or stress on different body structures. The pain may vary significantly and be felt as bone pain, nerve pain, or muscle pain, and its intensity ranges from mild to severe.
