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.
Tension headaches are very common, unfortunately, they're also among the most neglected and difficult headaches to treat. With a tension headache, the pain often starts at the back of your head and moves forward, so that it eventually includes your neck, scalp, and head.auses. Researchers aren't clear what causes a tension headache. For years, scientists thought that it was caused by tightening the muscles in your shoulders, neck, scalp, and jaw when you are tense. But new tests that measure muscle tension show that the muscles of people with tension headaches arenât any tighter.
