Information for Patients


Neck Injuries and Disorders

Any part of your neck - muscles, bones, joints, tendons, ligaments, or nerves - can cause neck problems. Neck pain is very common. Pain may also come from your shoulder, jaw, head, or upper arms.

Muscle strain or tension often causes neck pain. The problem is usually overuse, such as from sitting at a computer for too long. Sometimes you can strain your neck muscles from sleeping in an awkward position or overdoing it during exercise. Falls or accidents, including car accidents, are another common cause of neck pain. Whiplash, a soft tissue injury to the neck, is also called neck sprain or strain.

Treatment depends on the cause, but may include applying ice, taking pain relievers, getting physical therapy or wearing a cervical collar. You rarely need surgery.

Wounds and Injuries

Also called: Traumatic injuries

An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.
