The back is a strong, yet flexible machine made up of bones, disks, nerves, muscles, and ligaments. Not only does this complex structure support your head and neck and hold you upright, it also allows you to carry heavy loads, and to walk, dance, bend, and twist. Your backbone extends from the base of the skull to the tailbone, and is formed of more than 30 individual bones called vertebrae, which encircle and protect the spinal cord and nerves. The vertebrae are connected by fibrous bands of tissue called ligaments, and separated by spongy discs that actually cushion the bones. Back muscles that are attached to the vertebrae control movement.
Acute pain is sudden pain that goes away quickly, usually lasting for less than three months.
Most patients with acute low back problems recover spontaneously within a few days to a few weeks. If you experience acute back pain that does not resolve itself on its own within a few weeks, or if you have recurrent episodes of acute pain, see your doctor. After taking your medical history and conducting a physical exam, your doctor will determine the need for additional medical tests and diagnostic procedures such as x-rays and bone scans. Most acute lower back pain is due to musculoskeletal strain or sprain. Poor posture, sitting at a computer, incorrect lifting, or other improper movements or activities can trigger the pain.
