What Is Sciatica?

Sciatica describes pain and other symptoms that occur when the sciatic nerve or its nerve roots become irritated or compressed. The sciatic nerve runs from the lower back through the hips and buttocks and down each leg.

Unlike general lower back pain, sciatica often affects one side of the body and may cause discomfort that travels from the lower back or buttock into the leg.

Sciatica is a symptom rather than a condition with one single cause. A clinical evaluation can help identify what may be contributing to your symptoms and determine which care options may be appropriate.

Common Signs and Symptoms of Sciatica

Sciatica can affect people differently. Symptoms may range from mild discomfort to pain that interferes with everyday activities.

Common symptoms include:

• Pain That Travels Down the Leg

• Tingling or Pins and Needles

• Numbness

• Muscle Weakness

• Discomfort With Sitting or Movement

Symptoms can overlap with other conditions, so an appropriate evaluation is important to understand their possible cause.
