If the left arm is involved, a heart condition referred to the arm must be considered. Initial treatment is aimed at reducing friction on the irritated nerve. Lifting is minimized, a soft cervical neck collar is used, and exercise is avoided. Next, medication to reduce swelling of the nerve is ordered. Traction at home or with Physical Therapy is another option.
Diagnostic testing includes routine cervical spine x-ray.
The x-ray can show evidence of degenerative disk disease, bony spurs or destruction, but not new soft disk herniation. MR Imaging of the cervical spine or myelography with CT Imaging are best to image disks and to confirm a clinical impression that surgical intervention is necessary. Surgery is considered for patients who show increasing weakness, reflex loss, and often relentless pain. Results are best when there is strong evidence that one root is involved.
