The treatment approaches included standard nonsteroidal antiinflammatory drugs (NSAIDs), selective COX-2 inhibiting NSAIDs (Coxibs), exercise, manipulation, and mobilization.
Some of these methods do have some potentially life-threatening adverse effects. For example, NSAIDs can cause internal bleeding of the stomach or GI tract. And cervical spine manipulations have been linked with strokes. Either of these problems can be very serious (even deadly).
But for the most part, treatment for neck pain is helpful and not life-threatening. When used with the right patients, the results can be reduced neck pain, improved motion, and restored function.
