Causes Of Sciatica
Sciatica is the compression or inflammation of the sciatic nerve. Symptoms include lower back pain, buttock pain, and numbness, pain or weakness in various parts of the leg and foot.
The major causes of sciatica are:
- Poor postural alignment. Over 90% of patients presenting with sciatica symptoms report a positive outcome, once good alignment is restored.
- Mechanical. A physical obstruction or compression of the sciatic nerve, including bulging disc, herniated disc, osteophytes, severe osteoarthritis, severe stenosis, narrowing of the foramen and a vertebral fracture. Mechanical issues will commonly be identified in an MRI or other scan. Manipulation or mobilisation is not recommended.
- Combination of mechanical and poor alignment. Scans will diagnose a mechanical issue but poor alignment can inflame and irritate any underlying mechanical issue increasing a patients sciatic symptoms. Correcting your alignment can resolve or reduce your symptoms, avoiding the immediate need for surgery. If not, then surgery is often required to correct the mechanical issue.
If a patient presents with constant and consistent sciatica symptoms irrespective of activity for a period of a week or more, diagnosis is likely to be a mechanical issue.
If symptoms come and go, poor alignment is most likely the cause. If alignment is corrected and sciatic symptoms are still present then a MRI or scans should confirm a mechanical diagnosis.
Despite an underlying mechanical diagnosis, patients who correct their alignment prior to surgery report better post operative recovery and reduced joint injuries in the future. Finch Therapy provides a stable alignment outcome that lasts for months or even years. As the program is very gentle and non invasive we believe it is safe to do so but if you have any concerns you should check with your Neurosurgeon or GP.
Maintaining alignment will reduce chronic and acute injuries to your nerves, joints and muscles and can help to prevent the need for joint replacements and surgery later in life.
