The cause of neck pain varies for each individual. More recently, neck pain has been a result of poor posture as a result of looking down for extended periods at one's phone, laptop, or computer monitor. Even if you have a great workstation set up, extended periods of time using technology can add unnecessary stress to one's neck. Other causes of neck and/or shoulder pain can include whiplash injuries (from car accidents/sports injuries), arthritis, poor sleeping habits, muscle imbalances, and misalignments/subluxations of the bones in the neck.
