Cause
Neck pain can be caused by an activity
or injury that harms the neck or by another medical condition.
Activities that cause neck pain
Most neck pain is
caused by activities that result in repeated or prolonged movements to the
neck's muscles,
ligaments,
tendons,
bones, or
joints. This can result in a
strain (an overstretched or overused muscle), a
sprain (injury to a ligament), a spasm of the neck
muscles, or
inflammation of the neck joints.
These
activities include:
- Holding your head in a forward or odd position for long periods
of time while working, reading, watching TV, or talking on the telephone.
-
Sleeping on a pillow
that is too high
or too flat or doesn't support your head, or sleeping on your stomach with your
neck twisted or bent.
- Spending long periods of time resting your forehead on your
upright fist or arm ("thinker's pose").
- Work or exercise that uses the upper body and arms, such as
painting a ceiling or other overhead work.
Stress and focusing intensely on a task can contribute to
neck pain. Tension may develop in one or more of the muscles that connect the
head, neck, and shoulders. They may feel tight and painful.
Injuries that cause neck pain
The
spine consists of interlocking bones (vertebrae) and
discs that separate the vertebrae. The portion of the
spine that runs through the neck is known as the
cervical spine
. Muscles and ligaments in the neck hold the cervical spine
together. Injury to any of these structures may result in neck pain.
See pictures of the
neck
and the
vertebrae and discs
.
Minor injuries may occur from tripping or
falling a short distance or from excessive motion of the cervical spine. Severe
neck injuries may occur from
whiplash in a car accident, falls from significant
heights, direct blows to the face or the back or top of the head,
sports-related injuries, a penetrating injury such as a stab wound, or pressure
applied to the outside of the neck, such as
strangulation.
Pain from an injury may be
sudden and severe. Bruising and swelling may develop soon after the injury.
Sudden (acute) injuries can result in:
- A strain or a sprain in the neck.
- A break or dislocation of the spine. This may cause a
spinal cord injury that may lead to lack of movement
and feeling (paralysis). It is important to immobilize and move the
injured person correctly to reduce the risk of further injury. For more
information, see
first aid for a spinal injury.
- A ruptured disc (herniated disc) in the cervical spine.
If the rupture is large enough, the jellylike material inside the spinal disc
may leak out and press against a
spinal nerve. A herniated disc in the cervical spine
can also occur as part of aging. See a picture of a
herniated disc
.
Medical conditions that cause neck pain
Neck pain
may be caused by or related to another medical condition. This can
include:
- Conditions associated with increasing age, such as the
narrowing of the spinal canal (cervical spinal stenosis) and arthritis
of the neck (cervical spondylosis).
- Illnesses such as
meningitis, which causes inflammation around the
tissues of the brain and
spinal cord
, and the
flu (influenza). When neck pain is caused by flu, the
neck and the rest of the body tend to ache all over, but there is no severe
neck stiffness.
- Chronic conditions such as
fibromyalgia,
rheumatoid arthritis, or
ankylosing spondylitis.
-
Torticollis (wryneck). Torticollis is caused by severe
muscle tightness or a shortened muscle on one side of the neck, causing the
head to be tilted to one side. Torticollis is usually a symptom of another
medical problem.
-
Referred pain. Referred pain occurs when a problem in
one place in the body causes pain in another place. For example, a problem with
your jaw (temporomandibular disorder) or your heart (such as a
heart attack) can cause neck pain.
- Infection or a tumor in the neck area.
Side effects of some medicines include neck pain.
