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 Bengaluru, Karnataka
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.

Frequently Asked Questions
Will sciatica go away on its own?
Yes, most cases are self-limiting and improve within a few weeks with conservative measures such as gentle stretching, physical therapy, and anti-inflammatory medication, without ever needing injections or surgery. Persistent or worsening pain beyond several weeks warrants further evaluation rather than continued waiting.
When does sciatica require surgery?
Surgery is reserved for cases with significant or progressive leg weakness, loss of bowel or bladder control, or pain that fails to improve after several weeks of conservative treatment, since these signs suggest more serious nerve compression. A discectomy to remove the portion of disc pressing on the nerve is the most common surgical approach when needed.
Is sciatica the same as general lower back pain?
No, sciatica specifically refers to pain that radiates along the sciatic nerve's path from the lower back through the buttock and down one leg, often with numbness, tingling, or weakness, whereas general back pain stays localized to the back itself. This radiating pattern is what distinguishes sciatica and helps pinpoint the nerve involved.
What activities should be avoided during a sciatica flare?
Prolonged sitting, heavy lifting, and twisting motions tend to worsen nerve irritation, so modifying these activities temporarily while staying gently active, rather than complete bed rest, generally supports faster recovery. Physical therapy can guide which specific movements to avoid or modify during the acute phase.
Can sciatica come back after it resolves?
Yes, especially if the underlying cause, such as a disc problem or degenerative spine changes, isn't addressed through ongoing core strengthening and good posture habits. Maintaining physical activity, using proper lifting technique, and managing body weight all help reduce the chance of recurrence.
