The course of low back pain depends both on its cause and on how well you treat your back.
Most low back pain goes away within several weeks. But after you have had back pain once, you're more likely to have it again. Many people who recover have back pain again within a year, and most people will have it again sometime during their lives.
Long-lasting (chronic) pain not only makes you tired, irritable, and less productive and less active but also can trigger other problems. If your back pain causes you to use your body in different ways (for example, to limp or to sit differently), pain can develop in other areas of the body. Pain can also cause biochemical changes in your body that tend to keep the pain going. Without special treatment, you may get chronic pain syndrome.
