Most types of headaches are caused by maladjustment of the spinal cord especially in cervical region. When the vertebra have moved for any reason, they no longer support the head correctly. At such time, the underlying nerves are squeezed, which result in headaches. Chiropractic treatment is able to identify the misaligned spinal joints and through manipulations bring it back to its original position. This will release the pressure on the nerves and cure the headache.
