Pain felt in the back originate from the muscles, nerves, bones, joints, and other structures in the spine.
The pain may have a sudden onset or can be a chronic pain; constant or intermittent, stay in one place or radiate to other areas. It may be a dull ache or a sharp or piercing or burning sensation. The pain may limit flexibility or range of motion of the back and the ability to stand straight.
Back pain can be caused by a number of different problems with the components of the back. The back contains disks that are cartilage-like pads that act as cushions between the segments of the spine.
Upper Back Pain:
Any type of pain throughout the back side of the chest and upper abdominal area. Upper back pain is not as common because the thoracic spine does not move as much as the spine in the lower back and neck.
Upper back pain may last briefly or may be chronic, which is defined as lasting more than three months. The pain may be dull and throbbing or sharp and stabbing. You may be in constant pain, or perhaps the pain occurs only during a particular activity.
Upper back pain can occur as a result of trauma, sudden injury, strain or poor posture over time. A majority of these causes are due to muscle irritation or joint dysfunction.
Mid Back Pain:
The mid back is the area from the shoulder blades to the area of the rib cage; including the ribs, diaphragm, as well as spine.
Middle back pain may be described as a dull, annoying ache, or a sharp, acute pain. Middle back pain can radiate, or spread, to other areas of your body.
Spinal imbalances are the most common cause of mid back pain. This can occur when playing sports, lifting, bending, having poor posture, arthritis, disease, muscle strain, or trauma suffered in a car accident occurs.
Low Back Pain:
Pain in the lower back, above the buttocks
Acute or short-term low back pain usually lasts for a few days to a few weeks. Pain can be caused by a sports injury, work around the house or in the garden, or a sudden jolt such as a car accident or stress on spinal bones and tissues.
Chronic back pain persists more than 3 months and often long-lasting. The cause of this can be difficult to determine.
Pain can occur when someone lifts something too heavy or overstretches, causing a sprain, strain, or spasm in one of the muscles or ligaments in the back.
