Thunderclap headaches (a group of disorders that involves sudden, severe headaches with multiple causes).Spinal headaches (caused by low pressure or volume of cerebrospinal fluid, possibly the result of spontaneous cerebrospinal fluid leak, spinal tap or spinal anesthesia).
Sinus headaches (caused by inflammation and congestion in sinus cavities).Medication overuse headaches (caused by overuse of pain medication).
Some types of secondary headaches include:
Trigeminal neuralgia (as well as other neuralgias, all involving irritation of certain nerves connecting the face and brain). Pseudotumor cerebri (idiopathic intracranial hypertension). Pressure from tight headgear, such as a helmet or goggles. Persistent post-concussive symptoms (Post-concussion syndrome). Influenza (flu) and other febrile (fever) illnesses. Glaucoma (acute angle closure glaucoma). Giant cell arteritis (inflammation of the lining of the arteries). Dehydration (which is when the body doesn't have enough water and other fluids to work properly). Chiari malformation (structural problem at the base of your skull). Blood clot (venous thrombosis) within the brain - separate from stroke. Arterial tears (carotid or vertebral dissections). Possible causes of secondary headaches include: Any number of conditions - varying greatly in severity - may cause secondary headaches. Certain foods, such as processed meats that contain nitratesĪ secondary headache is a symptom of a disease that can activate the pain-sensitive nerves of the head. Some primary headaches can be triggered by lifestyle factors, including: Chronic daily headaches (for example, chronic migraine, chronic tension-type headache, or hemicranias continua). These headaches have distinct features, such as an unusual duration or pain associated with a certain activity.Īlthough generally considered primary, each could be a symptom of an underlying disease. Trigeminal autonomic cephalalgia (TAC), such as cluster headache and paroxysmal hemicraniaĪ few headache patterns also are generally considered types of primary headache, but are less common. Some people may also carry genes that make them more likely to develop such headaches. A primary headache isn't a symptom of an underlying disease.Ĭhemical activity in your brain, the nerves or blood vessels surrounding your skull, or the muscles of your head and neck (or some combination of these factors) can play a role in primary headaches. A primary headache is caused by overactivity of or problems with pain-sensitive structures in your head.
