Radiculopathy is a medical condition that occurs when a nerve root in the spine becomes compressed or irritated. This can lead to pain, numbness, or weakness in the areas of the body that the affected nerve supplies. Common causes include herniated discs, spinal stenosis, or injuries. Symptoms of radiculopathy often radiate along the path of the affected nerve, which may include the neck, back, arms, or legs. Diagnosis typically involves physical examinations and imaging tests, such as MRI or CT scans, to identify the underlying cause and determine appropriate treatment options.
