Headaches are a common problem in everyday life. Some experts believe that there is a type of headache related to wear and tear in the neck, termed a 'Cervicogenic Headache'. Dr Lavin, Neurologist, has previously written an article for Myelopathy.org on the subject. In this headache, symptoms are often intermittent, related to posture, and affect one half of the head.
Anecdotally, many of our Myelopathy Support members report headaches.... so perhaps it is not as uncommon as first thought? Room for further investigation certainly....
As part of the review from America, mentioned in our previous blog, the group looked at whether there were any screening questionnaires for Cervicogenic Headache.
They identified one such study. In this study, the researchers looked at the diagnostic criteria for Cervciogenic Headache, and compared how predictive of the condition each component was with respect to other forms of headache (such as Migraine).
Of the various features, the following were found to be associated with Cervicogenic Headache more than 75% of the time, compared to other headache conditions. (E.g. If 100 answer yes to statement 1, 75% will have a Cerviogenic Headache).
Major Symptoms and Signs
1) Pain triggered by neck movements and/or sustained awkward head positioning
2) Pain elicited by external pressure over the GON ( a nerve in the neck) or over C2-3 on the same side as the headache is experienced.
3) Shoulder and arm pain of a rather vague, non-radicular nature on the same side as the headache
Pain Characteristics
4) Pain episodes of varying duration or fluctuating, continuous pain
5) Moderate, non-excruciating pain, usually of a non-throbbing nature
Other Factors
6) Anaesthetic blockades of the GON or C2 nerve root
7) Sustained neck trauma a relatively short time prior to the onset
Less commonly associated features
8) Rarely occurring nausea, vomiting, and XII photo- and phonophobia
9) Ipsilateral oedema and, less frequently, ̄ushing, mostly in the periocular area
10) Dizziness
11) `Blurred vision' in the eye ipsilateral to the pain
12) Difficulty on swallowing
The criteria are designed to be assessed by a doctor and not self reported by patients, but they may be of interest as we are aware that headaches are a common topic of conversation at Myelopathy Support.
It is worth mentioning that Cervicogenic Headache remains a controversial headache type and many of these symptoms can be experienced in other forms of headache.
