Whiplash
Whiplash is a neck injury caused by a forceful, rapid back-and-forth movement of the neck, commonly occurring during car accidents. While most people recover within a few weeks, some may experience chronic pain and complications.
Overview
Whiplash is a neck injury caused by a forceful, rapid back-and-forth movement of the neck, commonly occurring during car accidents. While most people recover within a few weeks, some may experience chronic pain and complications.
Understand this condition
Whiplash affects the soft tissues, nerves, and bones of the cervical spine. The sudden force stretches or tears the muscles and ligaments in the neck beyond their normal range. This triggers inflammation and protective muscle spasms to stabilize the injured area.
Why it happens
It happens when rapid acceleration and deceleration transfer intense kinetic energy to the neck. This force can knock vertebrae out of alignment or damage intervertebral discs. Most cases resolve as inflammation subsides, but severe impacts can cause lasting nerve sensitivity.
Real-world scenarios

- •People may notice a dull headache starting at the base of the skull.
- •This can manifest as difficulty turning the head while driving at intersections.
- •People may notice tingling sensations traveling down their arms after a fall.
Common vs serious explanations
- •Minor muscle strain in the neck
- •Temporary ligament stretching
- •Post-traumatic muscle guarding or stiffness
- Cervical spine fracture or broken neck bone
- Herniated disc pressing on a spinal nerve
