Article excerpts about the
causes of Chronic headache:
What hurts when you have a headache? The bones of the skull and tissues
of the brain itself never hurt, because they lack pain-sensitive nerve
fibers. Several areas of the head can hurt, including a network of nerves
which extends over the scalp and certain nerves in the face, mouth, and
throat. Also sensitive to pain, because they contain delicate nerve
fibers, are the muscles of the head and blood vessels found along the
surface and at the base of the brain.
The ends of these pain-sensitive nerves, called nociceptors, can be stimulated by stress, muscular tension, dilated blood vessels, and other triggers of headache. Once stimulated, a nociceptor sends a message up the length of the nerve fiber to the nerve cells in the brain, signaling that a part of the body hurts. The message is determined by the location of the nociceptor. A person who suddenly realizes "My toe hurts," is responding to nociceptors in the foot that have been stimulated by the stubbing of a toe.
A number of chemicals help transmit pain-related information to the brain. Some of these chemicals are natural painkilling proteins called endorphins, Greek for "the morphine within." One theory suggests that people who suffer from severe headache and other types of chronic pain have lower levels of endorphins than people who are generally pain free.
