Sciatica is commonly characterized as mild to severe pain which radiates along a single or both legs, caused by the impingement or compression of the nerve roots in the lower back. Various types of injuries or conditions affecting the lumbar spine can result in symptoms of sciatica.

Sciatica is often referred to as radiculopathy, a medical term utilized to describe symptoms of pain, tingling sensations, numbness and weakness in the arms or legs as a result of nerve complications. If the nerve issues occur along the neck, it’s called a cervical radiculopathy. Because sciatica affects the lower back, however, it is called a lumbar radiculopathy.

Beginning at the back of the pelvis, or sacrum, the sciatic nerve is paired with five sets of nerve roots which then runs from the lower back, under the buttocks and down through the area of the hips and into each leg. Nerve roots are a great part of the body’s entire nervous system, functioning by transmitting pain and sensation to the different parts of the body. Radiculopathy can frequently develop when pressure is applied to the nerve roots as a result of an injury or condition, such as a herniated disc or a bone spur in the lumbar spine.
