Spinal pain overview
Pain affecting different areas of the spine
Spinal pain, or back pain, is very common, with an estimated 8 out of 10 people being affected by it at some point in their lives, and of these one in five go on to develop chronic back pain, that is ongoing pain that lasts for longer than three months.
Although it can affect people at any age, it tends to first develop between the ages of 20 and 40 and becomes a bigger issue with advancing age.
The spine is divided into three zones: the cervical spine which is at the top and incorporates the neck, the thoracic spine which is the mid-section and the lumbar spine which is the lower back.
Spinal pain is most common in the lumbar section, followed by the cervical spine. The thoracic spine is the least affected by spinal pain.
Common causes of spinal pain
Conditions and injuries that can affect the spine
The spine is an incredibly complex part of the body, comprising the spinal cord, protected within the bones of the spine (‘vertebrae’) and an array of muscles, tendons and ligaments, as well as the intervertebral discs located between the vertebrae.
Nerves exit the spinal cord via these intervertebral spaces. Pain can be associated with any one of, or a number of, these components.
Common causes of back pain include:
- Muscle spasms
- Spinal stenosis
- Nerve-related conditions
- Previous spinal surgery
- Muscle, tendon or ligament strains
- Inflammation affecting the joints between the vertebrae.
- Pain affecting the muscles and surrounding connective tissue.
- Degenerative changes affecting the spine
- Movement of one vertebra relative to another.
- Age-related changes affecting the intervertebral discs.
Spinal pain tests and diagnosis
How the cause of back pain is assessed
Generally speaking, imaging of the spine should not be a routine investigation, but should only be ordered if the doctor suspects there to be a fracture, infection, tumour or danger of damage to the nervous system.
The first step in diagnosing the cause of back pain is a review of symptoms and medical history. The doctor will examine the back to find areas of pain or tenderness, check range of motion and check for any nerve problems.
Blood tests may be recommended to find out if there may be other underlying conditions causing spinal pain, and if kidney stones are considered a possible cause of spinal pain, an ultrasound scan may be suggested.
In some cases, imaging tests such as X-rays, CT or MRI scans may be recommended. Of these, MRI is the most useful as it can show soft tissue and intervertebral discs clearly which X-rays and CT scans cannot, at least not as clearly.
