Sciatica

Sciatica occurs when the sciatic nerve is irritated, pinched or compressed. A number of conditions can affect the sciatic nerve, including:

• Spinal disc issues such as herniation (often called a ‘slipped’ disc) or degenerative disc disease both of which alter the disc structure and can cause pressure onto the sciatic nerve.

• Spinal stenosis - the area of the lower spine that houses the nerves is narrowed

• Osteoarthritis - the discs and cartilage between vertebrae are worn down and damaged

• Back injuries

• Pregnancy - additional weight, changes in body composition and the baby’s position can put pressure on the sciatic nerve

• Tumours, cysts or other growths

• Cauda equina syndrome - a rare, emergency condition that affects the nerves in the lower part of the spinal cord

Your OneWelbeck consultant will be able to make a diagnosis of sciatica by performing a physical examination, asking you questions about your symptoms, and performing some tests. Tests required may include imaging scans such as X-rays, MRI and CT scans. Electromyography (EMG), a test that measures nerve impulses and muscle response, may also be required to determine the severity of a nerve root injury.

The best treatment for sciatica depends on its severity. Mild cases may benefit from self-care treatments including exercises and stretches, hot and cold compresses and over-the-counter painkillers.

For cases that require specialist care, treatments include:

• Prescription medications including painkillers and muscle relaxants

• Physiotherapy

• Steroid injections

• Decompression surgery to remove portions of a vertebra or herniated disk to relieve pressure on the nerve

We are able to offer Sciatica appointments to referred paediatric patients aged 12-18. For full information on our paediatrics service, please visit our main Paediatrics page.
