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.
Cervicogenic headaches are headaches that originate from the neck, specifically from the base of the skull at the top of the spine. The headaches start out intermittently in the initial stages, and then slowly become continuous. Most cervicogenic headaches are caused by stress, fatigue, problems sleeping, back and neck injuries, poor posture and disc injuries. They are usually triggered by sudden neck movements and may be accompanied by dizziness and blurred vision.
