What is sciatic disc disease?
Sciatica is a condition that occurs when the sciatic nerve is compressed by a herniated disc.
What is the sciatic nerve?
The sciatic nerve is the longest and thickest nerve in the human body. It runs from the lumbar spine, through the buttocks and down to the foot, supplying nerve supply to a large part of the lower limb.
What is a herniated disc?
Between each vertebra in the spinal column is an intervertebral disc, which acts as a shock absorber. A herniated disc occurs when part of this disc shifts and compresses the nearby nerve roots.
How does sciatic disc disease manifest itself?
Typical symptoms of sciatic disc disease include :
- Radiating pain: The pain generally starts in the lower back and radiates down one leg, along the path of the sciatic nerve. It can reach the buttock, thigh, calf and even the foot.
- Tingling or numbness: These sensations can be felt in the area affected by the pain.
- Muscle weakness: In severe cases, muscle weakness may develop in the affected leg.
What causes sciatic disc?
The main cause of sciatic disc disease is a herniated lumbar disc. Other factors can also contribute to the condition, such as
- Ageing: Natural wear and tear of the intervertebral discs increases the risk of herniation.
- Trauma: Intense physical effort or trauma to the back can cause a herniated disc.
- Posture: Poor posture can put excessive pressure on the intervertebral discs.
How is sciatic disc disease treated?
Treatment for sciatic disc disease depends on the severity and duration of symptoms. It may include :
- Conservative treatments:
o Rest: It is important to limit activities that aggravate the pain.
o Medication: Non-steroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants can help relieve pain.
o Physiotherapy: Specific exercises can strengthen back muscles and improve mobility.
- Invasive treatments:
o Injections: Corticosteroid injections can reduce inflammation and relieve pain.
o Surgery: In the most serious cases, surgery may be required to remove the herniated part of the disc.
It is important to consult a doctor if you think you are suffering from sciatica. An accurate diagnosis will enable the appropriate treatment to be put in place.
