Neck pain and associated shoulder and arm pain are the source of a great deal of suffering and expense in lost time from employment. Most patients without objective neurological loss will improve with conservative treatment alone. Conservative treatment can consist of manipulation, cervical traction, cervical collars and analgesics. When symptoms persist or worsen over an extended period of time (4-6 weeks), further diagnostic evaluation is warranted. Diagnostic tests such as MRI, CT or occasionally myelography or discography can be performed. The most commonly found abnormality is a herniated cervical disk. Far less common are other causes such as spinal stenosis, nerve root entrapment or tumor.
