Headache:
Headache are extremely common - most of people have a headache at some time in their life. Headache is defined as a pain arising from the head or upper neck of the body. The pain originates from the tissues and structures that surround the brain itself has no nerves that give rise to the sensation of pain. The periosteum that surround bones; muscles that encase the skull, sinuses, eyes; and meninges that cover the surface of the brain and spinal cord, arteries, veins, and nerves, all can become inflamed or irritated to cause the pain of a headache. This pain may be a dull ache, sharp, constant, mild, or intense.
Causes of Tension Headache
The cause of tension headache is not known. WHO ( World Health Organization) estimates that in the developed world, 80 percent of women and 67 percent of men will experience this type of headache. The most likely cause is contraction of the muscles that cover the skull. When the muscle covering the skull are stressed, they may become inflamed, go into spasm, and cause pain. Common sites include the base of the skull where the trapezius muscles of the neck insert, the temples where muscles that move the jaw are located, and the forehead. There is little research to confirm the exact cause of tension headaches. Tension headaches occur because of physical or emotional stress placed on the body. For example, these stressors can cause the muscles surrounding the skull to clench the teeth and go into spasm. Physical stressors include difficult and prolonged manual labor, or sitting at a desk or computer for long period of time concentrating. Emotional stress may cause tension headaches by causing the muscles surrounding the skull to contract.
