Many possibilities: Back pain can have many causes. In addition to musculoskeletal issues, such as a strain, arthritis, slipped disc, etc., other causes can include most gynecologic issues, urinary issues, colon or other intestinal issues, and even heart and lung problems. Best to see your doctor as an examination is certainly necessary to find the cause of your back pain.
