Causes of Back Pain - Sciatica

Cliff Russell is a Registered East Grinstead Osteopath with years of experience helping people with Sciatica.

Sciatica is a term used to describe pain that radiates along the path of the sciatic nerve, which runs from the lower back, through the buttocks, and down the back of each leg.

Sciatica can be caused by a number of different conditions that result in irritation or compression of the sciatic nerve. While the pain associated with sciatica is most commonly felt in the legs, it can also cause significant discomfort in the lower back.

The most common cause of sciatica is a herniated or bulging disc in the lower back. The discs are located between the vertebrae in the spine and act as shock absorbers. When a disc herniates or bulges, it can press on the nearby nerves, including the sciatic nerve, causing pain, tingling, or numbness in the legs or lower back. The pressure on the nerve can also cause inflammation, which can further exacerbate the pain and discomfort.

Another common cause of sciatica is spinal stenosis. Spinal stenosis occurs when the space within the spinal canal, through which the spinal cord and nerves pass, becomes narrowed. This can occur due to the natural aging process or as a result of other conditions such as arthritis or degenerative disc disease. When the space within the spinal canal is narrowed, it can put pressure on the sciatic nerve, leading to pain and discomfort.

Sciatica can also be caused by a condition called piriformis syndrome. The piriformis muscle is located deep in the buttocks and is responsible for rotating the hip. When this muscle becomes tight or inflamed, it can irritate the sciatic nerve, causing pain and discomfort that radiates down the back of the leg. This type of sciatica is less common than that caused by a herniated disc or spinal stenosis, but can still be a significant source of back pain.

In addition to these common causes, sciatica can also be caused by other conditions such as spondylolisthesis, which occurs when one vertebra in the spine slips out of place and presses on the nerves, or spinal tumours, which can cause compression of the sciatic nerve.

The symptoms of sciatica can vary depending on the underlying cause and the severity of the condition. Common symptoms include pain, tingling, or numbness in the lower back, buttocks, legs, or feet. The pain may be sharp or dull, and can be described as a burning or electric sensation. Some people with sciatica may also experience muscle weakness in the legs, making it difficult to walk or perform everyday activities.

Diagnosis of sciatica is typically based on a combination of a patient's medical history, a physical exam, and imaging studies such as X-rays, CT scans, or MRI. Treatment of sciatica will depend on the underlying cause of the condition. In many cases, conservative treatments such as rest, physical therapy, and anti-inflammatory medications can help to alleviate the symptoms of sciatica. In more severe cases, epidural injections or surgery may be necessary to relieve the pressure on the affected nerve.

Overall, sciatica can be a significant source of back pain and discomfort. However, with appropriate treatment and management, many people with sciatica are able to manage their symptoms and maintain an active lifestyle. It is important to work closely with a healthcare provider to develop a treatment plan that is appropriate for your individual needs and goals.
