Back pain is one of the most common ailments; approximately 80% of the adult population will develop a significant episode of back/neck pain sometime during their life. Fortunately, most of these will spontaneously resolve. However, approximately 10% to 20% will develop into significant chronic and/or recurrent episodes of pain. Wear and tear conditions, such as degenerative arthritis and degenerative disc disease, are some of the most common causes. Poor posture and weak muscles may prevent healing. Muscle pulls and tears may also cause back/neck 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 causes of pain include infection, cancer, fractures, aneurysms, and/or internal organ problems.
