What Is Sciatica?
Sciatica is a condition that causes back pain resulting from issues with the sciatic nerve. The nerve is large and runs from the lower back towards the back of legs. An injury or pressure on sciatic nerve can lead to lower back pain that travels through the hip, buttocks, and ultimately to the leg
The Symptoms
Lower back pain extending through the hip and buttock and towards a leg is the major symptom of sciatica. The pain affects a single leg and gets worse on coughing, sitting, or coughing. Sometimes the leg may also feel weak, tingly, or numb. The symptoms of sciatica appear all of a sudden and may last for several days or weeks. Consulting one of the back specialists will help you to get the best treatment option.
Is it Sciatica or Other Back Pain?
It is not necessary that all types of back pain involve the sciatic nerve. In most cases, back pain may be the result of strain or overextending of lower back muscles. The major sign of sciatica is the way in which the pain travels down the leg and into one foot. The condition may feel like a very bad leg cramp. It may last for several days.
Who Gets Sciatica?
Age (Individuals between the age of 30 and 50 are more vulnerable to sciatica)
- Pregnant women (developing uterus puts pressure on sciatic nerve)
- Herniated disk
- Spinal degenerative arthritis
Major Causes
1. Herniated Disk
Disks are like cushions between spinal vertebrae. As one ages, these disks tend to get weaker and more vulnerable to injury. In some cases, gel-like structure of disk can push through its exterior lining and compress sciatica nerve roots. The symptoms may last over 6 weeks.
2. Spinal Stenosis
The vertebrae are vulnerable to natural wear and tear. It results in narrowing of spinal canal or spinal stenosis.
3. Spinal Tumors
Sciatica may result from tumors in rare cases. Tumors grow inside or along sciatic nerve or the spinal cord adding pressure on the spinal cord nerves.
