Burners happen in only one arm at a time. If both of your arms or one arm and a leg are hurt, you may have a serious neck injury, not a burner. Your doctor will then protect your neck and get x-rays. Burners get better on their own. You may need physical therapy to stretch and strengthen your muscles.
Some burners last a few minutes.
Others take several days or weeks to heal. This test can show that you have a burner and give an idea about how long it will last. You must have no pain, numbness or tingling. You must be able to move your neck in all directions. Your strength must be back to normal.
