Neck
Pain
As with all pain clinic assessments
of paramount importance is to exclude sinister
causes for the pain. These include cancer pains.
If such a cause is suspected or found then you will be referred
to an appropriate physician. This
can be subcategorised very much like pain
arising from the lower back with pain either being limited
to the neck or present also in any combination of head, arms,
shoulders and hands.
Another way of looking at the origin of neck pain is that it may
arise from the neck or cervical vertebral bones, the spinal ligaments
or the spinal musculature. Some will also argue that superficial
neck pain is a sign of pain arising from a cervical intervertebral
disc. This is discogenic pain. There is a theory abounding that
discogenic pain may be the main cause of what eventually becomes
fibromyalgia
or widespread body pain.
Pain
limited to the neck
The cervical intervertebral joints are prone to degenerative or
arthritic changes much the same as any other joint. The arthritic
changes may also be inflammatory as in rheumatoid arthritis or
ankylosing spondylitis.
This
latter disease is an inherited condition where painful inflammation
in the spine is eventually replaced by painless fusion of the
vertebral bones. The cervical facet joints can
be the source of neck pain although they are less recognised as
being so in most pain clinics. This is probably because it is
much more difficult to inject into them compared to the thoracic
and lumbar facet joints so fewer pain doctors undertake this type
of work. The risks are also greater with the underlying spinal
cord and the vertebral arteries close by. Instead they usually
prescribe painkilling drugs and concentrate on treating the superficial
trigger and tender points with steroid and even Botox injections.
TENS machines are also useful for some patients as are the topical
NSAID and capsaicin creams.
Pain
in the neck and arms
Whiplash injury with
ligament and joint damage, slipped discs in the neck, degenerative
arthritis in the neck and muscular neck injury with muscle spasm
can all lead to symptoms in the neck, head, shoulders and arms.
As a result, differentiating between an individual’s symptoms
to decide where there pain is coming from can be extremely difficult.
In addition, a patient may concentrate on neck and arm pain when
actually they hurt all over and actually have fibromylagia
or other such chronic
pain syndrome.
Slipped
neck discs are common and may lead to shooting
or aching pains in specific parts of the head, arms and specific
fingers. Associated symptoms may include weakness in the upper
limbs, pins and needles (parasthesiae or dysaesthesiae if painful)
or even numbness. Arthritic neck bones may also compress nerves
and give the same symptoms. If associated symptoms are severe,
bowel and bladder function are affected or the MRI scan suggests
an unstable spine with spondylolisthesis then referral to a spinal
surgeon may be necessary if one has not already been seen.
Nerves
from the neck form the Brachial plexus which goes on to give the
nerve supply to the arms, hands and upper chest wall. If this
is damaged or invaded by cancer then it will also give neuropathic
symptoms and signs.
Treatments
As with caudal and lumbar epidurals being effective for sciatica
so cervical epidurals can be effective for slipped neck discs
causing arm and hand pain. The principle is the same as well with
injection of steroid but this time even more care is required
because the spinal cord lies beneath.
Cervical epidurals can be repeated 3-4 times a year if necessary
but they should give good lengths of time of pain relief. Others
find TENS useful for their pains. Muscle spasms in the shoulders
are often responsive to Botox
injections if they do not respond to simple acupuncture or
trigger
point injections with steroid.
Headache
Headaches can be looked at as being caused by problems in the
head itself or resulting from problems in the neck and shoulders
being referred to the head.
Migraine
– most patients with migraine are treated
successfully by their G.P.s and neurologists and rarely come
to the pain clinic as a primary referral. Symptoms include changes
in mood with one-sided headache, sensitivity to light, visual
disturbance and sometimes nausea and vomiting. These headaches
can last for 4 to 72 hours. Less commonly they are associated
with an aura which describes associated visual disturbances or
even episodes of speech impediment or weakness. Treatment is with
specific drugs e.g. migraleve (sumatriptan)
Cervicogenic
Headache – secondary to pain from the neck.
Muscle spasm leads to irritation of the greater occipital nerves
and pain on one or both sides of the head felt only as far forward
as the forehead. Greater occipital nerve block with steroid is
often useful.
Tension
Headache – lasts 30 minutes to 7 days at a
time. These are felt on both sides of the head and are distinguished
from migraine as not being associated with nausea or vomiting
or light or sound sensitivity.
Cluster
Headache – This is severe one-sided pain affecting
the area of the eye and above and behind it. The pain lasts for
15 minutes to 3 hours. Attacks occur from one every other day
to 8 a day and are associated with symptoms such as nasal congestion,
excessive tears, runny nose, sweating, and swelling all on the
same side as the headache.
Attacks occur in clusters lasting 4 to 10 weeks. These are interspersed
by pain free periods of months
or years.
Treatment is mainly
with drugs such as migraleve and abstinence from causal factors
e.g. alcohol.
If the headaches occur 15 to 20 times a day and last for only
3-15 minutes then this is termed chronic paroxysmal hemicrania
and the drug indomethacin, an NSAID, is usually successful.
Analgesic
headache – Large doses of aspirin, paracetamol
or codeine used to treat headache can actually aggravate headache
themselves. The same is true with sudden withdrawal form migraleve
(sumatriptan). Therefore these painkillers should not be taken
everyday for headaches.
