Headaches are a commonly reported symptom and are known to affect 47% of the population, among which Cervical Headaches account for 15–20% of all chronic recurrent headache. Women are four times more likely to be affected than men (Racicki S et al., 2013). Cervical headaches, referred to as cervicogenic headache, are more commonly associated with a neck trauma such as a Whiplash injury (but not necessary).
International Headache Society (IHS) classified about 14 different types and subcategories of headaches. The headaches are classified under primary caused by vascular origin and secondary resulting from inflammation, head, and neck injuries. Cervical headache or Cervicogenic headache is of secondary type.
Cervical musculoskeletal impairment is a characteristic of cervical headaches (Jull G et al., 2007). Cervical headaches are usually confirmed from physical measures identifying musculoskeletal impairment. Impairments can include painful upper cervical joint dysfunction, restricted range of cervical extension movement, increased sternocleidomastoid activity, which is shown to have 100% sensitivity and 94% specificity in distinguishing a cervical headache from migraine and tension-type headache (Jull G et al. 2007).
Causes of Cervicogenic headache:
Cervicogenic headache is commonly caused by Cervical joint dysfunctions usually arising from the joints, muscles, ligaments, and soft tissues in the neck. Literature supports that the primary cause of dysfunction is at the C2-3 zygapophysial joints (Z joint pathology (Lord et al. 1996). Additional literature also supports cervical headache that can arise from dysfunction of the C2-3, C3-4 discs or facet joints, atlantoaxial and atlanto-occipital joints in the neck.
These dysfunctions are associated with neck trauma after a whiplash injury but are most often related to microtrauma from prolonged neck flexion or poor sustained habitual postures.
Often abnormal cervical spine posture is said to be associated with cervical headache. The researchers found that individuals with increased cervical lordosis had an increased likelihood of experiencing cervical headaches (Peter k et al., 2015)
Most common Cervicogenic headache symptoms :
- Headache is usually unilateral ( but the bilateral headache of cervical origin is also possible) and affects the head, neck, and face.
- Associated Suboccipital neck pain (however, also note that other headache types also frequently may have cervical symptoms)
- Pain or stiffness starts in the neck and spreads to the head
- The presence of non-throbbing headache usually starts in the neck, with episodes of varying duration of Long-lasting headaches from usually hours to days.
- Headache onset is related to mechanical factors from sustained posture, including prolonged sitting, reading, looking down and extended looking up positions.
- Other symptoms with cervical headache include dizziness, nausea, light-headedness, difficulty focusing, retro-ocular pain, and visual disturbances but are usually associated with very mild symptoms (Racicki S et al., 2013).
- Upper cervical joint restrictions and tenderness are often present and tested by physical examination.
Lifestyle factors related to headaches: Some of the lifestyle factors also can cause headaches like Stress, dehydration, Alcohol intake, Caffeine, lack of sleep, medications, high blood pressure, infections, hormonal factors related to menstrual periods and also precipitated by hunger, certain foods types etc.
Tension-type headaches are also more common and include band-like tightening, pressing pain. Tension-type headaches usually last from 30 minutes to 7 days, mild to moderate intensity, bilateral location, and do not aggravate physical activity. Tension-type headache has no associated features of nausea, vomiting, photophobia, or phonophobia.
Below are some of the conditions and symptoms that may be characteristic of Non-Cervical Headache origin. Patients presenting with these symptoms should seek medical consultation and are unlikely to respond to manual therapy.
- The onset of headaches prior to and without neck pain or stiffness (non-mechanical origin)
- Headaches of severe intensity uncontrollable by medications
- Progressive headache aggravated by lying down and sleep quite disturbed (from increased Intracranial pressure)
- Severe unilateral headaches lasting briefly can include cluster headaches, paroxysmal hemicranias, and trigeminal autonomic conditions. The pain duration may be as short as 2 minutes, with a frequency of 5 per day (IHS).
- Migraine headache with typical aura: symptoms include having flickering lights or spots in the visual field, pins and needles, numbness, sensation lasting less than 60 min.
- Migraine headache without aura include the pain of unilateral location, pulsating, moderate to severe intensity, lasting for a fixed period of 24-72 hours. Aggravated by routine physical activity and associated with nausea, photophobia, or phonophobia with the characteristics of chronic tension
- Vascular origin headache: Presence of regular distinct pattern headache lasting for a particular time, and usually, the symptoms resolve fully.

According to the Cervical Headache International Study Group, several headache characteristics are shared between the cervical headache and non-cervical headache groups and require proper identification.
Due to various locations of pain symptoms and severity of dysfunction, various treatment techniques healthcare practitioners use in the treatment of Cervical headache.
Treatments can include invasive and non-invasive techniques.
The invasive treatment techniques consist of injections, dry needling, and surgery (Racicki S et al. 2013).
The non-invasive treatment techniques include exercise, manipulation, mobilization, fascial connective tissue release or mobilization.
Physiotherapy Can Help With Cervicogenic headache:
Research has shown that physiotherapy can help cervical headaches and tension-type headaches by using a combination of the manual treatment approach and exercise therapy with lifestyle modifications to address your headache.
Your Physiotherapist may be able to perform a mechanical assessment to determine if the headache is cervical in origin, has a mechanical cause and determine the appropriateness for treatment and proceed with appropriate therapy.
Please contact a physiotherapy clinic near you if you think you are suffering from cervical headache for an assessment and management.
