What is Sciatica?

The most common cause is a herniated or slipped disk that causes pressure on the nerve root.he Sciatica nerve serves a vital role in connecting the spinal cord with the skin and muscles of the thigh, leg.
Back pain is sometimes linked with pain in the legs, and there may be numbness or a tingling feeling. This is called sciatica.Depending on where the Sciatica nerve is affected, the pain may also extend to the foot or toes.


  • Increased pain over time
  • Paresthesias in the affected leg
  • Loss of muscular strength in the affected leg
  • Loss of bowel and/or bladder function
  • Permanent nerve damage


  • Sudden, severe pain in the low back pain or a leg and numbness or muscle weakness in a leg
  • Pain after a violent injury, such as a traffic major accident
  • Trouble controlling bowels or bladder


Sciatica occurs when the sciatic nerve becomes pinched. The cause is usually a herniated disk in the spine or an overgrowth of bone, sometimes called bone spurs, form on the spinal bones. More rarely, a tumor can put pressure on the nerve. Or a disease such as diabetes can damage the nerve.


During the physical exam, a healthcare provider might check muscle strength and reflexes. example, you may be asked to walk on your toes or heels, rise from a squatting position, and lift your legs one at a time while lying on your back. Pain from sciatica will usually get worse while doing these moves.

Treatment / Management

  • Practicing good, erect posture
  • Engaging in exercises to increase core strength
  • Gentle stretching of the lumbar spine and hamstrings
  • Regular light exercises such as walking, swimming, or aquatherapy
  • Use of proper lifting techniques
Sciatica is a clinical diagnosis, and therefore, a thorough history and physical examination are necessary for a complete evaluation and diagnosis.
