Unfortunately back pain is common and affects most people at some point during their lives. It is often triggered by lifting something incorrectly, sitting badly, sleeping awkwardly, bending, having a fall, stress or from sustaining a sporting injury. This is known as acute (sudden onset) lower back pain. In most cases it is not due to a serious disease or a chronic back problem. Chronic back pain is measured by duration - pain that persists for more than 3 months and is often progressive. As with acute back problems, the cause of the pain can be unclear and this is known as non-specific lower back pain. The pain can range from mild to severe. This is the most common form of back discomfort in adults and the type of back problem I often see and treat regularly.
