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.
