WHY DOES THE HEAD ACHE?
Friday, July 8th, 2011Since almost everyone suffers from headache at some time, it is often not regarded as a disease, although clearly it is ‘disease’ (i.e. not being at ease). But since headache interferes considerably with the lives of significant numbers of people, it seems illogical to regard it as normal. However, the changes occurring in the body are subtle, so that it is exceedingly difficult to analyze changes taking place, even with sophisticated research tools. Often, no sooner has some abnormality been discovered, than it is shown to be only secondary to pain, or not to be present in all who supposedly have the same symptoms. By comparison, the understanding of an obvious abnormality such as an infected chest is simple, as not only can changes be seen on an X-ray, but the ’cause’ can be isolated by observing the germ in the laboratory.The fact that a number of people have a specific form of headache does not necessarily mean that the cause is the same in all of them. In the same way, a blocked nose and sore throat may be caused by infection with germs or by allergy; the symptoms can be identical but the treatment of each is very different. Treating a ‘runny’ nose due to hay fever with antibiotics is worse than useless.The situation in the classification of headaches is analogous, except that a good deal is known about the structures concerned with pain and the nerves which carry the sensation.
