It’s common for rear or side impact crashes to cause your neck to snap quickly. Injuries can range from mild neck strain, to dislocation of vertebrae (the bones of the spine). Mild neck strain may be treated with over-the-counter pain relievers. A dislocation or other serious vertebrae injury may require surgery. Whiplash symptoms can last several weeks. Recovery time after surgery will vary depending on the procedure needed. Full recovery can take months.
