Cervical radiculopathy is a condition caused by the compression or irritation of nerves in the neck region. This often occurs due to herniated discs, bone spurs, or degenerative changes in the spine. Symptoms may include pain, numbness, or weakness that radiates down the arm, depending on which nerve is affected. Diagnosis typically involves a physical examination and imaging tests like MRI or CT scans to identify the source of nerve compression. Treatment options may include physical therapy, medications, or, in severe cases, surgery to relieve pressure on the affected nerves.
