What is it? How is it treated?
It is usually not possible to know the exact cause of neck pain in the days or weeks after a car accident. We know the muscles and ligaments get strained and are probably inflamed, but they usually heal within six to ten weeks. Pain that lasts longer is usually due to deeper problems such as injury to the disc or facet joint, or both.

Multiple modalities are commonly employed to reduce low back pain. They are especially useful in alleviating acute low back pain (e.g. an intense, debilitating episode of low back pain) for the patient. Physical therapists or chiropractors usually use passive modalities.

Injury to the head may damage the scalp, skull or brain. The most important consequence of head trauma is traumatic brain injury. Head injury may occur either as a closed head injury, such as the head hitting a car's windshield, or as a penetrating head injury, as when a bullet pierces the skull. Both may cause damage that ranges from mild to profound. Very severe injury can be fatal because of profound brain damage.
