Simply, this is called a ruptured disc. Because of the close proximity of the disk to the spinal nerves, spinal nerve compression does occur due to the disk herniation. Many muscles in the back an also contribute to back pain. These muscles are attached to the spinal column, pelvis, and extremities. They serve to provide additional support to the back and neck.
Many conditions cause back pain.
Some of these are congenital, such as scoliosis, while others are a result of injury or trauma to the back. What to expect when you see your doctor. He or she will ask you a number of questions about your back pain including when it started, how long its been present, what type of symptoms you're experiencing, and what you've done to relieve the discomfort. X-ray studies of the back allow the physician to visualize bony structures, evaluate general alignment, and in some cases, determine the cause of the back pain. An MRI scan of the spine provides a clear view of the discs in the back, as well as the nerves and other soft tissues.
