The sciatic nerve is actually the longest nerve in our body. When there is an inflammation, it produces a very uncomfortable pain which extends from the ribs to below the knee.
When we rest, it helps to alleviate the problem temporarily, but it does not resolve it.
Sciatic Nerve Pain Causes
- Sciatica can result from a variety of causes, though the main one is a herniated disc that compresses the nerve root; this is responsible for around 90% of all cases. Other common causes are lumbar stenosis, spondylolisthesis, arthritis, and tumors. Sciatic nerve pain can also be caused by pressure arising from a dysfunctional sacroiliac joint or the piriformis muscle. Pregnant women can also experience sciatic nerve pain.
- Between 5% and 10% of people who suffer from lower back pain have sciatica. Typically, it occurs mainly in the 45 to 64 age group and its risk factors are associated with height, mental stress, and smoking. It is also more likely to occur in people who carry out frequent lifting and driving.
