Neck pain is a common problem, affecting many adults at some time in their lives, that can involve just the neck and shoulders, or it may radiate down an arm. The pain can be dull or feel like an electric shock into your arm. Other symptoms such as numbness or muscle weakness in an arm can help pinpoint the cause of your neck pain. It can be cause by muscle strain, worn joints, nerve compression, injuries or diseases such as rheumatoid arthritis.
