Radicular

Radicular refers to the root of a nerve, specifically the part of the nerve that is closest to the spinal cord. Radicular symptoms can be felt in the part of the body that is served by the affected nerve. Radicular pain is often referred to as radiculopathy, or sciatica when it is felt in the lower back, hips, buttocks, and legs.

Causes

Radicular pain is caused by compression, inflammation and/or injury to a spinal nerve root. This is often due to a condition such as a herniated disk, spinal stenosis, or a bone spur. The pain is often deep and steady, and can usually be reproduced with certain activities and positions, such as sitting or walking.

Symptoms

Radicular pain may occur in the back or neck, and extend into the arms or legs. It is often described as sharp, shooting, or burning, and it may be accompanied by numbness or weakness. In severe cases, patients may experience loss of coordination or motor function.

Diagnosis

Diagnosis of radicular pain begins with a physical examination and medical history. Other procedures and tests may be needed to diagnose the cause of the radicular pain, such as a CT scan, MRI, or electromyography (EMG).

Treatment

Treatment of radicular pain depends on the underlying cause, but may include physical therapy, medications, injections, or surgery. Conservative treatment options are usually tried first, before considering surgery.
