First of all take a complete and thorough medical history.
I really emphasized to patients:
- Do not think in black and white terms about possible causes of headaches.
- Do not get fixated on just one possibility otherwise we will lose a lot of diagnostic time -
- Do look for multiple causes and try to join the dots as much as possible.
Think very broadly about possible trigger factors including, but not limited to, the possible combinations of causes listed below:
Think magnesium deficiency:
One of the common causes which I see for headaches in adults is magnesium deficiency. Then when I mention possible magnesium deficiency I may be told:
" I have already tried magnesium". But what this statement really tells me is that I need to be thinking about: how can it be that this person is taking a decent magnesium supplement but still has a lot of symptoms of magnesium deficiency? In other words: why is this patient not absorbing magnesium properly.
Think Hormonal scarcity or imbalance:
Let's carry this on a little bit: as well as having symptoms of magnesium deficiency, this imaginary patient is female aged 38, and always gets headaches coming up to a period - then maybe we need to assess and think about oestrogen and progesterone relationships.
Think possibly unrecognised perimenopause or menopause:
These conditions may go unrecognised sometimes over several years
Think subtle unrecognised sinus infection:
All just because an individual has a 'normal' CT or MRI of his or her sinuses I will not necessarily be convinced that the sinuses might not be playing a part.
Think chemical sensitivity:
Some headache patients may present with chemical sensitivity - very sensitive to perfumes, smells , chemicals, modest amount of alcohol. This suggests that perhaps the liver detoxification biochemistry may not be working well.
Think: Might the person's liver not be detoxifying efficiently?
Think: Might there be a significant food intolerance ?
