Sciatica is a medical condition that causes pain due to inflammation or irritation of the sciatic nerve. Most people with the condition experience pain in the lower back and behind the thigh. The sciatic nerve is the largest and longest nerve in the body, running from the lower back through the gluteus and into the thigh. People with sciatica describe the pain as burning, tingling, or sharp. Often, sciatica flare-ups resolve on their own after some time.
Pain in the lower back is often the first symptom reported by people with sciatica. They may describe it as deep and radiating or tingling. Herniation of spinal disc that presses on the sciatic nerve is the cause of this sensation in more than 90% of cases. Treatment for this symptom often involves pain medications. Most of the time, the condition will resolve on its own without further medical intervention.
