Some ways to prevent neck stiffness include the following:
Many causes of stiff neck are not preventable.
The long-term effects of a stiff neck depend on the underlying cause. For example, a person who received a minor whiplash from a car accident may recover completely without any further effects. Torticollis may cause a person to suffer lifelong pain and a decreased ability to move about. A person with meningitis may recover from the infection, may suffer lifelong limitation in movement, or may die from the infection.
The cause of the stiff neck will determine if others are at risk. A person who has injured his neck is not contagious. A person with an infection, such as meningitis, may be contagious to others.
