Sciatica – causes, symptoms and support that relieves nerve pain
Sciatica is not a diagnosis in itself, but a symptom of nerve damage in the lumbar spine. The pain often radiates from the lower back down into the leg and can be due to a herniated disc, inflammation or muscular overload.
What is sciatica?
The sciatic nerve is the largest nerve in the body and runs from the lower back down to the foot. When the nerve is pinched, for example due to a herniated disc, pressure occurs that causes pain, numbness or weakness in the leg. The problem can also be caused by muscular tension, so-called “false sciatica”.
Common causes & risk factors
Sciatica can be triggered by a herniated disc pressing on the nerve, inflammation of the sciatic nerve, or overuse of muscles in the pelvis and hip. Risk factors include sedentary work, heavy lifting, poor lifting technique, obesity, and lack of core strength. Long-term incorrect loading or one-sided movements can also contribute.
Symptoms
- Pain in the lower back that radiates down the leg, sometimes all the way to the foot
- Worsened pain when coughing, sneezing, or straining
- Stiffness and reduced mobility in the lower back
- Numbness, tingling, or decreased sensation in the leg or foot
- Decreased muscle strength or reflexes in the affected leg
When should you seek medical attention?
Contact healthcare if you experience severe or persistent pain, loss of sensation, decreased strength in your leg, or difficulty controlling urine or stool.
Recommended protection & support
A back support can be very helpful for sciatica. A stabilising back support relieves the lower back and reduces pressure on the nerve, and the compression in the back support increases circulation and provides pain relief. Always combine with appropriate activity and avoid prolonged immobility. See all our products for the back and lower back here.
