Back pain is one of the most common ailments; approximately 80% of the adult population will develop a significant episode of back pain sometime during their life. Fortunately, most of these will spontaneously resolve. However, approximately 10% to 20% will develop into significantback pain which might last long or come in episodes. Wear and tear conditions which occur with age are more common causes. Low back joint restrictions and/or sacroiliac joint restrictions are also a common cause of acute low back pain. Muscle pulls and tears may also cause low back pain, but usually the symptoms from muscular causes are short-lived. Weak muscles, poor flexibility, and poor posture all aggravate underlying conditions and worsen symptoms. Uncommon and more serious causes of pain include infection,cancer, fractures, aneurysms, and/or internal organ problems.
