Common Causes of Back Pain
Muscle strains: Strained muscles, tendons, or ligaments, as well as inflamed joints, may cause pain along the spine.
Spasms: Muscle spasm, a common response to injury, is actually a protective response designed to immobilize the painful area and prevent further damage.
Disc Degeneration: The normal wear-and-tear process that affects all discs throughout the spine. The pain associated with the condition often resolves as the body naturally heals across the worn disc(s).
Osteoarthritis: A degenerative joint condition that affects nearly everyone past age 60. Overloading, injury, and aging can cause deterioration of cartilage, the protective tissue that covers the surface of the joints of your vertebrae.
Sciatica: Pain that may occur in your leg due to inflammation or compression of nerves in your lower back.
Osteoporosis: A condition that causes porous and brittle bones, leading to a gradual weakening of the skeleton and a greater risk for bone fractures that are both painful and debilitating. People older than 50, particularly women, are prone to osteoporosis.
Herniated disk: A condition that occurs when normal wear and tear or exceptional strain causes a disk to rupture. Bulging of disks is common and often painless; it becomes painful when excessive bulging causes fragments of the disk to break off, putting pressure on nearby nerves.
Fibromyalgia: A chronic syndrome that produces aches, tenderness, and stiffness in the muscles and joints where tendons attach to the bones.
