Chronic low back pain (CLBP) is a condition characterized by persistent or recurring pain in the lower back. There are a number of different synonyms for the condition, including chronic lower back pain, lumbar spine pain, and chronic backache. Other terms used to describe CLBP may depend on the underlying cause of the pain, such as degenerative disc disease, herniated disc, or spinal stenosis. Some people may also use more general terms to describe the pain, such as persistent or recurring back pain. Regardless of the specific term used, CLBP can be a challenging condition to manage and requires careful diagnosis and treatment to achieve optimal outcomes.
