Despite significant advancements in anesthetic science and a comprehensive understanding of anesthetic mechanisms, it remains impossible to completely predict or eliminate potential complications associated with anesthesia. One of the most severe complications is anesthesia-related mortality.

Back pain after spinal anesthesia is usually just a mild discomfort and will quickly heal through the body's natural recovery mechanisms in the first few days. However, if the spinal anesthesia process damages the ligaments in the lumbar region, it can still cause back pain for the patient, although this is quite rare.
