Complications

Most people who have whiplash feel better within a few weeks and don't seem to have any lasting effects from the injury. However, some people continue to have pain for several months or years after the injury occurred.

It is difficult to predict how each person with whiplash may recover. In general, you may be more likely to have chronic pain if your first symptoms were intense, started rapidly and included:

• Severe neck pain
• More-limited range of motion
• Pain that spread to the arms

The following risk factors have been linked to a worse outcome:

• Having had whiplash before
• Older age
• Existing low back or neck pain
• A high-speed injury
