https://www.medilaw.tv - medical illustrations, Neck pain can be caused by a sudden overload injury, such as from rapid extension-flexion during a car accident, lifting or pulling a heavy object, or from a blow to the head. Pain can also be caused by chronic strain from prolonged poor posture or an awkward sleeping position.

The tissues in the neck that can cause pain include
bone -- bruising or fractures
intervertebral discs -- bleeding, intradiscal circumferential tears, radial tears alone or with herniation of the disc, or disc avulsion
facet joint - synovial capsule bruise or tear, bleeding, cartilage fracture
spinal cord -- compression, bruising, or tear
nerve roots -- stretching, compression, bruising, or tear
ligaments and tendons -- inflammation or tear
muscles -- inflammation or tear.

Forceful injuries can cause overstretching and tearing of tissues. This leads to bleeding, inflammation and swelling over the following day or two that can cause additional pain. When there is an injury to a muscle and its adjacent structures, the muscle contracts and causes surrounding muscles to contract in an attempt to splint and protect the damaged area. This contraction can however, cause even more pain.

Before you become consciously aware of pain, your spinal cord processes the incoming pain message from your body, then sends the message on to your brain. Then you become aware of the pain message. Repetitive pain messages from the body can trigger changes to the way the spinal cord processes these pain messages, causing them to be amplified in the spinal cord before being relayed to the brain. This leads to an increase in your sensation of pain from the same pain source. This is why persisting damage can become perceived as increasingly painful and disabling over time.

Symptoms of cervical spine disorders can include
neck, shoulder, scapular or arm pain
muscle stiffness
visual disturbances such as blurred vision
tinnitus or ringing in the ears
neurologic impairment such as numbness, weakness or heaviness in the arms, paresthesia or pins and needles, unsteadiness with walking, bladder or bowel dysfunction, disturbed concentration and memory

Conservative or non-surgical treatments include
continuing normal activities
correct posture
medication to reduce pain, inflammation, muscle spasm and sleep disturbance
relaxation techniques
low impact, flexibility, strength and endurance exercises
physical therapy modalities such as heat, ice, massage, ultrasound, laser, short-wave diathermy, neck traction
trans-cutaneous electrical nerve stimulation
temporary soft collar support
body movement work
occupational therapy, and
workstation ergonomic evaluation.

The goal of therapy is to restore function with an emphasis on improving your strength, endurance and flexibility. Pain should be treated early and intensively. Underlying medical conditions should be treated to assist rehabilitation.

Surgery may be advised if there is damage to the spinal cord or the nerves leaving the spinal cord, or if there are any unstable vertebrae.

Whiplash happens when your neck moves backwards and forwards, or side to side, too quickly. It happens most often in car accidents, and can injure the facet joints, intervertebral discs, ligaments, nerves or muscles in the neck. Sometimes the resulting neck pain and stiffness is not felt until awhile after the accident. Usually, the pain is mild and doesn't interfere with normal activities, and gradually gets better. However, up to ten percent of whiplash injuries become long-term problems. Radiological scans of the cervical spine are often normal as the injury is too small to detect. Sometimes Whiplash-Associated Disorder can occur, involving headaches, nausea, vomiting, confusion, dizziness, shoulder and arm pain, numbness, weakness and paresthesia or pins and needles.

People who continue their normal daily activities heal faster than people who stay at home and become inactive.
