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.
These are rare. More common causes include tooth problems or ear problems. Of the actual headache causes of pain, there are a few types of headaches that can be causing your symptoms. Tension headaches are headaches caused by muscle strain around the head. Migraines are a common form of headache. One type of headache often associated with eye pain is what is called a cluster headache.
