Motor vehicle accident
Approximately two-thirds of people involved in motor vehicle accidents develop symptoms of whiplash, according to Dr. Dan Murphy. The symptoms usually do not develop until two to 48 hours after the injury. Patients with whiplash injury may complain of pain and stiffness in the neck, extending into the shoulders and arms, upper back and even the upper chest.
Headaches
If you have a headache, you’re not alone. Nine out of 10 Americans suffer from headaches. Research shows that spinal manipulation may be an effective treatment option for tension headaches and headaches that originate in the neck.
