Medical Musings, Health Hypotheses & Therapeutic Thoughts
.Headaches can be tricky. There are a lot of reasons to get headaches, these are divided into categories.
These are headaches that are not caused by some underlying medical condition, so they are benign (non-life threatening), although migraine sufferers may disagree! More than 90% of headaches fall into this classification. These include:
Tension-type headaches (TTH) - the most common cause of headaches. It has been estimated that up to 90% of headaches are TTH.
Migraines - the second most common primary headache. We do not yet fully understand why migraines occur, but current thinking is that they are caused by an interaction between nerve/brain and blood vessel abnormalities.
Cluster headaches - extremely severe, sufferers who are mothers have often described the pain as worse than childbirth. Again, we are not sure what causes them, but it seems it may be something to do with a region of the brain called the hypothalamus.
Cervicogenic (meaning coming from the neck) headaches.
Result from trauma or some other underlying medical condition, such as infection, tumours, or bleeding in the brain. These account for less than 10% of headaches, but some causes may be life-threatening. Early diagnosis of these causes is important to avoid life-threatening complications.
Your osteopath is trained in recognising the different types of headaches, and will refer you on to the appropriate specialist if there is any concern that you may be suffering from a secondary headache.
However, let us assume that you have had your headache assessed by an appropriate healthcare professional. When that headache strikes, what can you do? Read on for our self-help tips and tricks...
1. Rest in a quiet, preferably dark, room
This can be effective for migraines, as well as TTH/cervicogenic headaches. As stress is one of the biggest factors in many headaches, having a rest can help both with the stress, and help tense, tired muscles to relax. TTH and migraine sufferers are also often overly sensitive to sound or light (or both).
Sit or lie down in a quiet, darkened or dimly-lit room. Try to relax the muscles of the neck, shoulders and back.
2. Have a glass of water
Dehydration can cause headaches, or make them worse. Keep yourself well hydrated to avoid these (and for a host of other reasons as well!). Remember, by the time you feel thirsty, you are already dehydrated. As little as 2% loss of body water content can cause loss of mental alertness and bodily fatigue, and it has been estimated that many of us do not even notice our thirst until we are moderately dehydrated (6-10% of body water).
(For reference, above 15% is considered severe dehydration, and may even result in death)
3. Breathing/Relaxation exercises
These work on the same principle as resting in a darkened room, by helping to reduce stress and muscle tension.
Take several deep, long breaths. As you breathe out, feel tense and sore areas relax and get heavy. Bonus points for imaging a peaceful scene (go to your happy place!).
4. Simple stretches and movements.
Phew. This is a big category, so we are only going to give a few examples. If you want more exercises that are tailored to you and your issue, ask your osteopath at Moreland Road Clinic about a personalised exercise program!
(a) Drop your chin down towards your chest, then slowly rotate your head in a half circle, first one way, then the other. Do not put your head backwards, as this compresses the joints in the neck, and tenses the very muscles we are trying to relax.
(b) Bend your head gently to the side. You want to feel a gentle pull in the muscles on the side of the neck. You can use your hand to help guide the head, but do not pull on it strongly or sharply.
(c) You can also intentionally (gently) contract muscles to help them relax. Think of it as bringing them a bit more back under conscious control. This is very effective in exercise (b), above. When you (e.g.) take the head off to the side, gently push back against the controlling hand. Do not use more than 5-10% of your strength - the point is to engage the muscles, not make them work hard. You can do the same thing, gently pressing your forehead into the palm of your hand (This will help relax the muscles in the front of the neck), or the base of the skull backwards into your hand (for the muscles at the back).
(d) Lie on your back, with a rolled up towel where your skull meets the top of your neck. Tuck your chin in, and gently press your head down onto the towel. Your should feel stretching and gentle pressure in the head/neck junction.
(e) Roll your shoulders in nice wide, slow circles. This helps to stimulate blood flow to the tight, sore muscles around the shoulders, upper back and neck, and will help them relax.
Another big topic! We will only give a few examples here. For more techniques, ask your osteopath for advice...
Self-massage is often difficult as it is hard to reach the areas you need to. However, headaches are probably one of the best issues to self-massage, as you should be able to reach most parts of your head and neck (if you can't, maybe you should book an appointment with your friendly neighbourhood osteopath to look at your shoulder problem!).
Use the finger pads (flats), not the tips - you want a nice, comfortable sensation, nothing too 'poke-y'.
(a) Describe gentle circles on your temples, the muscles above the ears (Yes! You have muscles there! You may have noticed them if you have ever smiled too hard for too long), and the side of the jaw. Target any particular painful spots, you will probably find they are tender to the touch as well. Keep it gentle!
(b) Place your thumbs near the base of your skull. Find the thick columns of muscle that run just on either side of the spine, and slide off them to the outside. You should feel these little depressions (hollows) where the neck meets the base of the skull. Press inwards and upwards until you feel a bit of discomfort. Using the pads of your thumbs, massage gently in small circles (keeping the inwards and upwards pressure).
(c) You can also try lifting your scalp up away from the head - if you have long hair, this is easy. Take a broad clump in each hand and gently lift upwards. You should feel almost instant relief. Combine with some gentle circular movements (again, with the finger pads) over the scalp, paying special attention to the sore bits.
NOTE: If you have a willing accomplice, get them to do these exercises for you. That way, you are not using the muscles in your shoulders and arms, which will make the techniques more effective.
6. Try heat and/or cold
A hot shower, or moist heat to the back of the neck may help to relieve the symptoms of tension headaches. Alternatively, try a cold pack (Always wrap cold packs in a towel or similar, so there is nothing too cold making direct contact with the skin) placed on the sore spots (e.g. temples, forehead, base of skull).
If either of these are uncomfortable/hurt, stop! The aim here is to reduce pain!
7. Over-the-counter (OTC) medication
A quick note: osteopaths are not qualified to give advice on drugs in general, so always consult your doctor or pharmacist about any medications you want to take.
Over-the-counter (OTC) drugs such as ibuprofen (e.g. Nurofen), paracetemol (e.g. Panadol), sodium diclofenac (e.g. Voltaren), naproxen sodium (e.g. Naprogesic) and aspirin may all help with headache pain. Interestingly, caffeine seems to make the effects of some of these more effective and rapid, which is why many OTC medications include it. However, please note that caffeine may be a trigger for migraines in sufferers. Also note that using any headache medication for more than three days in a week may cause medication-overuse headaches (these would be secondary headaches). Please consult your GP if you find you are needing medication this often.
Without going into too much detail, there are broadly speaking two main methods of acupuncture for headaches. Traditional Chinese acupuncuncture involves placing fine needles in specific points around the body. These points may be anywhere (i.e. not necessarily close to your head, in the case of headaches), and are chosen based on the idea that pain, dysfunction and disease are due to energy imbalances in the body. Trigger point dry needling (the technique used at Moreland Road Clinic) uses the same needles (and often techniques), but the points chosen are in tight and sore muscles that your therapist has identified as contributing to your headache pattern (so will normally be around the head, neck, shoulders and upper back).
Research indicates that these needles stimulate blood flow to the area, helping tense muscles relax, and may also help to release endorphins, the body's natural painkillers; both of which can help with headaches, particularly TTHs.
Anyone who knows me and my treatment approach has probably been wondering when this one would sneak in!
Research indicates that moderate exercise can help reduce the number and intensity of headaches (and by the same token, lack of exercise can predispose towards chronic headaches). This is probably because exercise is another way of releasing those endorphins (those wonderful pain-killing chemicals!), as well as promoting good overall health. Stronger muscles don't have to work as hard to do their normal job (this includes the heart as well!), and a more efficient cardiovascular system (heart, lungs, blood vessels etc) reduces the stress and strain on your body in general.
Aim for 150 minutes (two and half hours, or half an hour five days a week) of moderate intensity exercise, something that (a) gets your heart rate up a bit and (b) you enjoy!
(b) is really important - if you do not enjoy it, you are less likely to maintain a long-term regime.
Finally, I would like to talk about when to see your doctor about your headaches.
Please contact your healthcare professional if:
-your headaches are extremely frequent, or start increasing in frequency, or last more than a few days.
- Please seek advice if your headaches are accompanied by change in co-ordination or balance, fits, faints, blackouts, seizures, confusion, blurred/double vision, numbness, severe nausea or vomiting, dizziness or vertigo, fever, stiff neck, or shortness of breath.
- If your headache is sudden, severe, occurs immediately after an accident (especially head trauma), or is "the worst you've ever had", seek immediate medical attention.

New research on acupuncture in helping pain
New research being conducted by Melbourne hospitals has found that acupuncture is as effective as medication in the treatment of lower back pain, migraines and acute ankle injuries.
In the randomised controlled trial, participants who went to the Emergency Departments with these ailments were randomised to receive either a) acupuncture alone, b) pharmacotherapy alone (medication including Endone, Panadeine Forte, Voltaren and Valium) or c) a combination of acupuncture + pharmacotherapy.
According the an interview with one of the lead researchers published in The Age, the results suggest that acupuncture is a safe and effective in improving pain management; after one hour of treatment, the level of pain relief was the same for each of the three groups. Also, those patients who had acupuncture tended to have a shorter stay in hospital. These findings may be helpful for patients who do not want to take medications (e.g., pregnant), or would like alternative pain management choices. The results also help inform the impact that acupuncture treatment may have upon health resource utilisation in Emergency Departments.
The final results are still being prepared for publication, but you can view the study protocol for the trial by clicking here.
Acupuncture & Dry Needling
Acupuncture is based on an Eastern conception of how the body, health and disease works, where energy, or 'qi', flows along channels called meridians. Imbalances in this energy flow are thought to cause 'dis-ease'. Traditional acupuncture involves the placement of needles into acupuncture points (or 'acu-points'), which are specific points along these meridians that help to balance this flow, and hence restore health.
Dry needling is a specific form of acupuncture in which the needles are inserted into 'trigger points', which are dysfunctional areas of muscle, which form discrete, tender nodules or bands which a skilled therapist can identify using their sense of touch, or palpation (and the fact that when they touch them, you say 'ow'!!). Dry needling helps to resolve these trigger points, which are so-called because they often 'trigger' pain or sensations in other parts of the body.
Dry needling has been shown to be effective in the treatment of myofascial (muscle and connective tissue) pain and acute injuries.
The Wikipedia page on trigger points is not bad, if you want some more information.
Speak with your osteopath if you think this may be relevant to your condition...
In previous years, migraines were thought to be a disorder of the blood vessels. More recently, it has been conceived of a response to pain stimuli, that is, dependent of structures outside the brain.
Positronic emission topography (PET) scans of patients experiencing the premonitory phase of migraine (before the headache actually sets in) shows that several areas of the brain are activated. This is significant, because "[b]efore this, all the imaging of migraine has been during the headache and the question has risen as to the degree to which what's happening in the brain is just a response to pain, or is something more fundamental, a part of the process of the migraine," said Dr. Goadsby, study author. "By studying the premonitory symptoms, you get rid of that question because these patients don't have any pain."
Further, a new literature review confirms that migraines are linked to structural brain changes (Warning! Fairly in-depth article that talks about parts of the brain etc.). This challenges previously held notions that migraines are 'benign primary headaches', with no long-term consequences for the brain. The analysis also showed that the association between migraines and these structural brain changes are stronger in those patients who suffer from migraine with aura.
