Sciatica Specialists in Karur, Tamil Nadu

What is Sciatica?

Sciatica is a term for pain that radiates along the path of the sciatic nerve, the longest nerve in the body, which runs from the lower back through the hips and buttocks and down each leg. It occurs when the sciatic nerve becomes compressed or irritated, most commonly by a herniated disc in the lower spine or bone spurs pressing on part of the nerve. The pain typically affects only one side of the body and can range from a mild ache to sharp, burning discomfort that makes standing, sitting, or walking difficult. While often self-limiting and resolving within a few weeks with conservative treatment, persistent or severe cases may indicate significant nerve compression requiring further evaluation.

Causes of Sciatica

Sciatica most commonly results from a herniated or bulging disc in the lumbar spine pressing directly on a nerve root that feeds into the sciatic nerve. Other causes include spinal stenosis, which narrows the space around the nerve roots, bone spurs from spinal arthritis, and less commonly a condition called piriformis syndrome, in which a muscle in the buttock compresses the nerve. Risk factors include obesity, prolonged sitting, physically demanding occupations involving heavy lifting or twisting, and age-related degenerative changes in the spine.

Symptoms of Sciatica

pain radiating from the lower back through the buttock and down the back of one leg, sharp, burning, or electric shock-like pain, numbness or tingling along the nerve pathway, muscle weakness in the affected leg or foot, pain that worsens with prolonged sitting, sudden pain when coughing or sneezing, difficulty standing up or walking normally

Treatment & Types of Sciatica in Karur, Tamil Nadu

Most cases improve with conservative measures including short-term rest, gentle stretching and physical therapy, and anti-inflammatory or muscle relaxant medications to manage pain and inflammation. Epidural corticosteroid injections may be used to reduce inflammation around the affected nerve root in more persistent cases. Surgery, such as discectomy to remove the portion of disc pressing on the nerve, is reserved for cases with significant or progressive weakness, loss of bowel or bladder control, or pain that fails to improve after several weeks of conservative treatment.

Sciatica is not a single disease but a symptom pattern classified by its underlying cause: disc-related sciatica from a herniated or bulging lumbar disc pressing on a nerve root, the most common cause; spinal stenosis-related sciatica from narrowing of the space around the nerve roots, more common in older adults; and piriformis syndrome, a less common cause where a buttock muscle compresses the nerve rather than a spinal problem. It is also described by duration as acute, typically resolving within weeks, versus chronic, persisting or recurring over months, which influences whether conservative care or further intervention is pursued.
