The majority of primary headaches are associated with muscle tension in the neck. Today, Americans engage in more sedentary activities than in the past, and more hours are spent in one fixed position or posture (such as sitting in front of a computer). This can increase joint irritation and muscle tension in the neck, upper back and scalp, causing your head to ache. Research shows that spinal manipulation – one of the primary treatments provided by Dr.Cormier– may be an effective treatment option for tension headaches and headaches that originate in the neck.
