A headache is pain anywhere in the region of the head or neck. It can be a symptom of a number of different conditions of the head and neck. The brain tissue itself is not sensitive to pain because it lacks pain receptors. Rather, the pain is caused by disturbance of the pain-sensitive structures around the brain. Several areas of the head and neck have these pain-sensitive structures, which are the cranium, muscles, nerves, arteries and veins, subcutaneous tissues, eyes, ears, sinuses and mucous membranes.
The most Common Types of Headaches:
Tension headaches: This is a very common headache called chronic daily headaches or chronic non-progressive headaches, tension headaches are the most common type of headaches among adults and adolescents. These muscle contraction headaches cause mild to moderate pain and come and go over a prolonged period of time.
Migraines: The exact causes of migraines are unknown, although they are related to blood vessel contractions and other changes in the brain as well as inherited abnormalities in certain areas of the brain. Migraine pain is moderate to severe, often described as pounding, throbbing pain.
Mixed headache syndrome: Also called transformed migraines, this is a combination of migraine and tension headaches. Both adults and children experience this type of headache.
Cluster headaches: The least common — although the most severe — type of primary headache, the pain of a cluster headache is intense and may be described as having a burning or piercing quality that is throbbing or constant. The pain is so severe that most cluster headache sufferers cannot sit still and will often pace during an attack. The pain is located behind one eye or in the eye region, without changing sides.
Sinus headaches: Sinus headaches are associated with a deep and constant pain in the cheekbones, forehead, or bridge of the nose. The pain usually intensifies with sudden head movement or straining and usually occurs with other sinus symptoms, such as nasal discharge, feeling of fullness in the ears, fever, and facial swelling. Upper cervical misalignments are associated with sinus headaches.
Most headache suffers find relief after one or several chiropractic adjustments as the nerve input is rebalanced.
