Nerve damage?: Your question suggests mechanical neck problems, perhaps from the injury, perhaps arthritis or deteriorated discs. Nothing you say (you do not mention numbness, tingling, pain shooting down arm or elsewhere) would fit with nerve damage. To find out more, you must see a physician such as an orthopedist to have examination and radiologic tests.
