CAUSES OF HEADACHES: MEDICINES

Many medicines can cause headaches, Sometimes these are ‘purely’ side-effects -what in medical terms are called idiosyncratic read ions; a patient, gels a headache while taking a particular drug, whereas other people generally don’t. Idiosyncratic reactions tend to be specific to a particular drug in a particular patient, and usually the onset, of the headache is quite clearly related to the time when he or she started taking the medicine.

Some groups of drugs used in the control of blood pressure can cause headaches. As part of their normal action they alter the muscle tone in the arteries, which are the high pressure side of the circulation. Control of blood pressure is by means of muscles lining the walls of the smaller arteries (the arterioles). If these muscles relax, the bore of the arteriole gets bigger; if they relax too much, blood at a higher pressure than usual can flow through to the organ the artery supplies. In some cases this distends the organ unpleasantly, causing pain. This is particularly important in the case of those arterioles which supply the brain. Certain drugs which make the muscles in these arterioles relax cause a pounding headache to develop. The most noticeable drug to do this is glyceryl trinitrate (GTN), which is commonly used under the tongue to abort attacks of angina (transient heart pain).

GTN works by dilating the arteries of the heart so that more blood can flow through to the heart muscle; however, the same action also happens in the arteries supplying the brain. As his heart pain diminishes, the patient also gets a bounding headache for a short period of time, as blood enters the brain under higher pressure than usual. Although with ordinary GTN this bounding headache always goes away quickly, other slow-release nitrates taken by mouth act on the heart for a longer period – and can also produce headaches in susceptible people.

Other drugs used to control blood pressure can cause headaches as a side-effect, especially if they act by reducing arteriolar muscle tone. Many drugs used to control blood pressure act in this way, but the sensitivity of individual patients varies considerably and what may cause terrible side-effects in one may not affect another at all.

Again, the cure is simple – avoid the offending drug. However, don’t suddenly
discontinue a prescribed drug without first talking to your doctor. This can be very
dangerous especially if you’re taking something like beta-blockers. It’s usually of
little value to try to treat headaches caused by specific drugs. It’s much better to
avoid the culprit drug, and change to an alternative preparation.

The contraceptive Pill can exacerbate existing migraines, or even (rather

dangerously) cause them to start in a patient who previously didn’t have migraines.

ANXIETY AND DEPRESSION: SELF-HELP

Self-help in anxiety/depression has three main parts. First of all, be prepared to admit that you’re depressed; secondly, don’t wallow in it, but get professional help; and, finally, start helping yourself to get out of it. This is not the same as ‘pulling yourself together’, which doesn’t work, mainly because it’s directed at the wrong things.

Recognising that you have a psychological cause for your headache is the first step towards healing it. If you are constantly striving to prove that there is a physical cause as a way of evading your responsibility to tackle your psychological problems, then you will make no headway. For some reason society tends to make out that people with psychological problems are evil or guilty, while those with physical problems are not. It really isn’t like that at all. True, you may have made decisions which, with hindsight, yon realise have contributed to your own current unhappiness. But for many sufferers from psychological illnesses, sufferings have been imposed from outside – the woman who was abused as a child; the adolescent who doesn’t love himself because his parents never really loved him; the man who is never allowed to show his anger because anger was always taboo in the family. Psychologically speaking, depression is often in-turned aggression -anger that you have not been able to express and so you turn it in upon yourself. So just because there is a psychological cause doesn’t mean that you are necessarily guilty; certainly, no more than if you had broken a leg skiing.

The second part of self-help is to recognise that although you are depressed you mustn’t wallow in it. Those who are depressed can get terribly self-absorbed with their depression and after a time some of them, as the saying goes, enjoy ill-health. Once you start wallowing in it you self-perpetuate the illness, and if you continue with the self-pity you’re likely to find that you quickly start running out of friends.

The third self-help method is honestly and courageously to face up to the things that are bothering you. Often it is an unspoken subconscious fear that you are too frightened to approach; perhaps it’s the fear of death; or that you can’t adjust to your sexuality; or you feel worthless as a result of being unemployed; or maybe you just feel unloved and unlovable. Courageously going headfirst into whatever problem is bugging you is often the quickest way to get out of those types of depression which are purely psychological in origin. Trying to evade the problem merely prolongs the issue and will lead you into more misery.

This is not easy to do. Facing up to those fearsome problems that are so hard to handle that you try to forget about them and bury them in your subconscious, is a very frightening activity, and you will need a lot of emotional support to do it. Tackling deep-rooted, fearsome problems like this is often where professional guidance and counselling come in.

Finally, make sure you get enough exercise. The apathy of depression is quite enough to stop you doing things, but exercise really can make you feel a lot better. Physically speaking, exercise releases the body’s own morphine-like chemicals (the endorphins) inside the brain, and these contribute to an increased sense of well-being. In addition, exercise uses up the extra adrenalin that will be swilling round your system if you’re anxious.

Depression often has its roots in in-turned aggression – an inability to vent anger. Very often the condition can be improved by learning how to appropriately dissipate it. Assertiveness training is part of this technique – learning how not to be trampled on can be very important. It is all about making sure that you are able to put your point of view forward and be listened to. Some people were never taught to be assertive; they find themselves doing what others want simply because they’ve never learned to stand up for themselves.

Physical contact is often a necessity in cases of depression. We humans need the constant physical encouragement of human contact, and families and spouses can often help by making a point of touching. The hand on the arm, the arm round the shoulder, the kiss, the cuddle; these all say ‘You’re important to me, you’re valuable in yourself – sentiments that the depressed person longs to hear.

It will help considerably to express your feelings more often. In depression the emotions often get buttoned up, and expressing them can help (particularly as these emotions can be very strong in depression). In our stiff-upper-lip society, it’s not always easy to let your emotions out, and expressing what you feel in art, music or dance may help. Art, dance and music therapy can be extremely helpful .

Although you might think that religion would be a consolation in depression -and sometimes it is – some depressed people perceive their religious beliefs as a burden rather than as a liberation. This is often tied in with a sense of guilt, worthlessness or failure. It is important to realise that these fears are a reflection of your depression, not an indictment of your beliefs.

WORK-RELATED HEADACHES’ CAUSES: BIOLOGICAL AGENTS

Fungi sometimes grow in air-conditioning systems, particularly where humidifiers are used, as the warm, wet conditions inside the humidifiers are ideal for promoting fungal growth. Contaminated air-conditioning and ducted warm-air heating can both pump large amounts of air polluted with millions of fungal spores around the building, and anyone who is allergic to these spores will react to them. Hay fever-like symptoms which start off at the time the air-conditioning or central heating is switched on may, in fact, be due to allergy to fungal spores sprayed into the air in this way.

Treatment is principally by recognising the cause of the problem and avoiding it where possible. Better ventilation may be all that is necessary. Proper anti-fungal treatment of air-conditioning systems; anti-allergic treatment such as antihistamines, etc. may be needed; in severe cases of allergy to fungal spores, desensitising injections can be given, but only through your local hospital. Homoeopathic desensitisation may also work.

CAUSES OF HEADACHES IN CHILDREN: EYE PROBLEMS

At least some headaches in children occur because of unsuspected eye problems. Squinting or focussing difficulties cause headaches when they are minor, because the child can compensate for the problem by tensing up the eye muscles or peering. This leads on to tension in the muscles of the eye and face, and to tension headaches. Major degrees of abnormality in the eyes don’t cause headaches, simply because the child can’t compensate by tensing up his muscles, so he doesn’t try.

Every year many children are unexpectedly diagnosed as being short-sighted when they and their parents didn’t think that anything was wrong. Often it’s only spotted because the child doesn’t seem to be doing well at school. Then someone thinks to check whether she can read the blackboard – and she can’t. The trouble is, if the child’s vision has always been that way she doesn’t know any better; she thinks vision is like that for everyone, so she doesn’t complain.

Minor degrees of squinting can also remain undiagnosed for a considerable time, especially where the child can normally compensate for the squint by extra muscular action. Note also that astigmatism (an inability to focus on horizontal and vertical lines at the same time) is a particularly potent cause of headaches.

MENOPAUSAL HEADACHES: COMPLEMENTARY TREATMENT

Complementary therapies can help deal with some of the secondary effects of the menopause.

Acupuncture can stimulate the body to deal more effectively with anxiety, depression, stress and irritability. It is supposed also to improve the balance of hormones, which will reduce the symptoms of the menopause. Headaches and migraine can he relieved by treatment to produce the body’s natural painkillers (the endorphins).

Aromatherapy can have a soothing effect – particularly techniques involving bath and massage. Analgesic oils such as lavender and camomile can be used to massage the head, shoulders and neck in order to remove tension and improve circulation. Headaches and migraine can be treated in this way. Clary sage is said to help balance hormones.

An osteopath or chiropractor can reduce the headaches and migraines triggered by stress or neck problems, reducing nervous pressure and tension.

A clinical nutritionist would probably suggest supplementary pituitary glandulars. Avoid spices, alcohol, caffeine and smoking, and reduce your fat intake – all of which help prevent headaches, by reducing the number of potential trigger factors.

A naturopath will suggest a healthy diet, exercise and regular sleep. Various dietary supplements might be recommended; in particular, the IS vitamins, and Vitamins C and E.

An in-depth consultation would be required for a homoeopath to effectively relieve the symptoms of menopause. Cimicifuga might be suggested for psychological symptoms (which can just as easily cause headaches), sanguinara for headaches and hot flushes, subphylum for tension and anxiety, and lachesis for headaches.

Sage has an effect on the oestrogen levels and can be used for problems associated with hormone imbalance. Angus castus, false unicorn, oats and St John’s wort can all be drunk, or taken in tinctures. Skullcap may ease anxiety or depression. Geranium oil is said to affect hormone balance, and the essential oil of rose is supposed to have a toning effect on the reproductive system in general.

Vitamin E is said to keep your reproductive organs healthy.
