Spinal headaches are caused by leakage of spinal fluid through a puncture hole in the tough membrane (dura mater) that surrounds the spinal cord. This leakage decreases the pressure exerted by the spinal fluid on the brain and spinal cord, which leads to a headache. Spinal headaches typically appear within 48 hours after a spinal tap or spinal anesthesia.
They are caused by muscle tension in the neck, shoulders and head. Problems in the neck, such as whiplash, or abnormalities of the spine, such as you have, can cause pain and tension in the neck, which in turn can cause headaches. Cluster headaches are defined as multiple recurrent attacks of severe, usually unilateral (one side of the head) pain.
