Spinal headaches are caused by leakage of spinal fluid through a puncture hole in the membrane 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 12 to 24 hours after a spinal tap or spinal anesthesia. Sometimes epidural anesthesia may lead to a spinal headache as well. Although epidural anesthetic is injected just outside the membrane that surrounds the spinal cord, a spinal headache is possible if the membrane is unintentionally punctured.
