| Chronic pain patients more often
than not are the most challenging in physicians’
practice; medical management of those patients is
usually obstinate and fruitless causing both, physician
and the patient, frustration. Every time when I
open a new chart I remember my old professor saying:
“ Chronic pain treatment requires combination
of science and art. Usually more art…”
Chronic neck and back pain is
the most common cause of disability in the United
States in persons younger than 45 years, and it
is the third most common cause of disability in
those older than 45 years (1). There are over
15 million office visits every year for mechanical
neck and low back pain in the United States (2).
Lack of physical activities, increased body weight,
limited ambulation, trauma, accidents, and repetitive
injuries to the spine result in back pain. 90%
of acute back pain resolves in 6 weeks without
any intervention. However, the remaining 10% will
become chronic back pain and cause significant
disability and have a negative impact on patient’s
quality of life (2). Famous professor Gordon Waddell
called back pain the 20th Century a Medical Disaster
(3, 4). The situation with back pain has become
so serious that the US Government declared 2000-2010
as bone and muscle decade. The correct diagnosis,
treatment and rehabilitation of musculoskeletal
disorders, osteoarthritis and back pain became
the issues of national importance.
Despite continuous research we still don’t
have a consensus how to treat chronic pain. Family
physicians, primary care providers frequently
ask questions about the best management for people
suffering from neck, upper back, and low back
pain; and this is why Alternative Medicine Clinic
designed an innovative pain management protocol
that combines traditional and not so traditional,
ie. alternative methods of treatment. Our protocol
includes not only the newer medications, but also
therapeutic injections, herbs and acupuncture
and other high tech modalities that become routine
and well accepted by the practicing community
of MN.
The purpose of this article is to review the comprehensive
methods of pain management in patients with chronic
pain that are recommended by American Pain Association,
American Academy of Physical Medicine and Rehabilitation
and other well-respected professional organizations
(4-7).
1. Detailed physical examination
begins with careful analysis of the patient’s
past medical history, current symptoms, family
history, and all medications he or she had been
taking in the past, their therapeutic effectiveness
and side effects. X-ray studies of the neck and
low back spine are usually recommended for an
accurate diagnosis and determination of the stage
and extent of the pathological changes in the
vertebral bodies, tendons, intervertebral disks
and corresponding nerve roots. If it is necessary,
medical providers can proceed with a more sophisticated
imaging study like CT or MRI, but those studies
are usually reserved for confirmation of radiculopathy
and more serious neurological and orthopedic conditions
like spinal stenosis, advanced facet artropathy.
2. Electrodiagnostic Study like
nerve conduction study and electromyography are
important tools in our Program. Based on the current
research and clinical data, electro diagnosis allows
us to get objective data about the function of your
nerve roots, peripheral nerves and muscles. Nerve
conduction study includes small electrical impulses
of motor and sensory nerves in your legs and arms.
The nerve response registered at the computer screen,
and the detailed analysis of its waveform provides
accurate information about the nerve functioning.
Electromyography involves the placement of the small
disposable needle-electrode in the examined muscles
and registration of the muscles activity at rest
and on contraction. When done by an experienced
physician-electro diagnostician, nerve conduction
study and electromyography is relatively quick (last
for 45-60 minutes) and well tolerated (8, 9).
3. Medications. There are several
pharmacological groups of medications that were
proven to be useful in the management of neck
and back pain. Well known traditional medications
like Tylenol and Aspirin might be used in mild
arthritic pain.
Non Steroidal Anti-Inflammatory (NSAIDs)
are important in controlling more severe cases
of arthritic inflammation in the small spine joints,
(i.e., facet joints). Those medications, so called
COX-I inhibitors, inhibit the special enzyme called
cyclooxygenase (COX) type I. Working on this enzyme,
those medications can stop the inflammation cascade
and help with pain. Unfortunately the current
research demonstrates that Ibuprofen (Motrin),
Naproxen (Aleve), and Indocine have side effects
causing gastric upset, discomfort, and even bleeding
when chronically used (10, 11).
The newer class of non steroidal anti-inflammatory
medications is COX-II inhibitors, medications
that block cyclooxygenase (COX) type II. Some
of the medications from this group, Bextra and
Vioxx, were called off the US market because of
cardio-vascular side effects, but, in general,
COX-II inhibitors are effective and well tolerated.
Celebrex is the only
FDA approved COX-II inhibitor that is on the market.
Mobic (Meloxicam) is
atypical COX-II inhibitor that is also effective
in patients with generalized osteoarthritis as
well as small spine joints arthritis. This medication
can be used for a long time in patients with different
comorbidities and polypharmacy.
Steroid medications.
Steroids are potent anti-inflammatory medications
and can be useful in controlling back pain. Oral
use of these medications is limited to acute back
pain that is caused by disc herniation with nerve
root compression. In acute cases Medrol dose pack
is usually prescribed. The pack contains methylprednisolone
that should be used over a one week period while
daily tapering the dosage.
Antidepressants such
as TCAs (tricyclic antidepressants)
and SSRIs (selective
serotonin reuptake inhibitors) are helpful in
certain types of neuropathic pain. Neuropathic
pain is defined as pain caused by spinal stenosis,
disk herniation or other lesions of the peripheral
or central nervous system. Spinal stenosis is
narrowing of the spinal canal and is usually caused
by disc degeneration or arthritis of facet joints
in the back or neck. Radicular pain is the pain
caused by irritation of the spinal nerves (nerves
coming off the spinal cord). Usually inflammation
occurs around the irritated nerve and causes back
pain radiating to the legs when it is in the lumbar
spine. Radicular pain is perceived as neck pain
radiating to the arms (12).
TCAs such as amitriptyline
(Elavil) and Nortriptyline (Pamelor) are both
effective for neuropathic pain. However these
medications can cause sedation, dry mouth, urinary
retention, increased heart rate, hypotension,
and constipation, especially in elderly patients.
SSRIs are well tolerated
compared to TCAs. SSRIs inhibit the reuptake of
norepinephrin and serotonin which is believed
to play an important role in the mechanism of
neuropathic pain. Venlafaxin (Effexor), Duloxetine
(Cymbalta) and Preballin (Lyrica) are well proven
to be effective for neuropathic pain and are the
most commonly used SSRIs in our clinic.
Anticonvulsants also
known as antiepileptic medications are medications
initially invented for prevention and treatment
of seizure disorders, but these medications have
been also used for neuropathic pain (13). The
most commonly used antiepileptic medication for
pain is Gabapentin (Neurontin) that is usually
well tolerated, but in some patients might cause
excessive sleepiness. Lyrica is a new medication
with a promising high effectiveness and favorable
side effects profile.
4. Opioid Medications: Opioids
are very potent pain killers and they are also
known as narcotic analgesics. Research and scientific
literature demonstrated that Opioids are helpful
in chronic neck and low back pain in certain patients
(5). However there are potential side effects
with long-term opioid use. Many patients are concerned
about the potential risk of addiction with these
medications. When Opioids are used for pain control
under the physician’s supervision, the risk
of addiction is rare. Other side effects of Opioids
are constipation, nausea, sedation, urinary retention
and respiratory depression, but usually these
side effects are manageable.
Medical providers should assess every patient
very carefully in order to decide whether the
patient is qualified for long-term opioid therapy.
Every physician and clinic should have clear guidelines
focused on initial patient evaluation, type and
dosage of medications prescribed, frequency of
ongoing follow up office visits.
Emphasis should be done on long acting opioid
medications for chronic neck and back pain since
these medications stay longer in your system and
are more effective for chronic pain problems.
Short acting Opioids should be used for the breakthrough
pain only in addition to long acting Opioids and
non opioid medications.
5. Herbal and natural medications.
Our patients often ask about the natural alternatives
to non-steroid and steroidal anti-inflammatory
medications. There is a huge variety of natural
alternatives and herbal dietary supplements on
the market, but in comprehensive pain management
program should include natural formulas with a
proven clinical effectiveness and favorable side
effect profile. Our first choice is a combination
of Chondroitin, Glucosamine, and MSM in combination
with Microlatin. Microlatin is a newer kid on
the block and is produced from dairy products.
We also recommend generalized conditioners like
Gingko Biloba, Guarana, Saw Palmetto, Sea Buckthorn
(popular Russian herb) and other Chinese folk
medicine formulas.
6. Topical medications and ointments.
Part of the comprehensive pain management program
includes topical ointments recommended for skin
application. Those transdermal formulas, so called,
compounding medications, are special ointments
prepared by the pharmacy according to physician’s
prescription. They usually contain a combination
of non-steroidal anti-inflammatory medications,
topical anesthetics, and muscle relaxants. It
is wise to have a special agreement with a pharmacy
that will prepare those compounding medications
for the particular patient. Additionally, we might
recommend use Capsaicin cream, made from red chili
pepper. Bioactive substances of red chili pepper
block the substance “P” and by then
reduce pain (14). 5 % Lidoderm patches made from
a special gel and release the numbing medication
Lidocaine within 12 hours.
7. Invasive procedures (injections):
Epidural Steroid Injections,
also known as cortisone shots. Steroid mixed with
local anesthetic (numbing medication) injected
directly into the epidural space under fluoroscopic
guidance. Epidural space is the space in spine
between the spinal cord and the posterior bony
parts of the spine. By using this technique, physicians
avoid the potential side effects of steroids when
given orally, and we increase the efficacy of
the medication by delivering it to the exact place
where the inflammation occurs. Epidural steroid
injections are useful to control the symptom and
facilitate recovery. You can have 3 or 4 epidural
steroid injections in a year.
There are different techniques of performing
epidural injections, such as interlaminar way
or transforaminal way. In both of these techniques
the medication is given directly into the epidural
space. The interlaminar or the translaminar way
is when we give the injection at the midline into
the epidural space on your back. If we give the
medication slightly off from the midline, we call
it transforaminal epidural steroid injection.
The transforaminal technique also called selective
nerve root injections, usually targets a certain
nerve root coming off the spine.
If physician believes that pain is coming from
the small joints called facet joints in spine,
he might inject the steroid medication into these
joints under fluoroscopic guidance. Like all the
other joints in the body, facet joints degenerate
with aging, become arthritic and cause pain. These
facet joints in conjunction with discs in your
spine carry most of your body weight. Sometimes
after automobile accidents and whiplash injuries,
there could be a misalignment between the small
facet joints in the neck which could cause significant
pain, headaches, decreased range of motion and
disability. Steroid injections into these joints
can facilitate the rehabilitation and faster recovery.
(15)
Other injections and Invasive spine
procedures include discograms, IDET (intradiscal
electro thermal therapy), nucleoplasty, vertebroplasty,
radiofrequency ablation (RFA) and implantable
therapies such as neurostimulation, and intrathecal
drug delivery therapies. All these procedures
are done under fluoroscopic guidance. With fluoroscopic
guidance, the risk of complications is minimized.
These procedures are highly effective when used
in appropriate patients.
8. Botulinum Neurotoxins (BoNT) Injections
(chemodenervation). One of the newer
treatments of muscular pain and spasms is BoNT
intramuscular injections. BoNT are natural bioactive
substances, a product of Clostridium botulinum
microorganism. There are 2 types of neurotoxins,
type A, Botox and Type B, Myobloc. In big doses
BoNT might be poisonous, but in small doses prescribed
by physician BoNT is an excellent and safe tool
to control muscle spasm and pain. Recent research
proved that nerve inflammation or arthritic facet
joints in the spine could cause pain, and local
muscle spasm, cervical dystonia might be effectively
treated with BoNT injections (16). BoNT injections
are safe, effective, well-tolerated, but expensive.
Injections are usually done under the guidance
of special electromyographic device that allows
physician to identify the most spasmodic and inflamed
muscles needed to be treated. The usual chemodenervation
procedure takes 15-30 minutes depending on the
amount of painful muscles followed by ice application
for half an hour. The injections are not painful
and tolerated well. The effect of pain relief
and muscles relaxation last for several months,
then injections might be repeated as needed.
9. Prolotherapy (rejuvenative injection
therapy). Another part of comprehensive
pain management program is prolotherapy (sclerotherapy)
or so called ‘Canadian injections’.
Prolotherapy is an injection therapy that helps
to accelerate the collagen synthesis inside impaired
ligaments and restores their tendon’s elasticity.
Research and clinical experience proves that inflamed
injured tendons and ligaments are unable to stabilize
the joint or spine and might be a source of constant,
dull aching (17). The idea of this therapy is
an injection of a proliferant solution inside
the impaired structures in order to rejuvenate
the ligamentous tissue and naturally stabilize
the joint. Prolotherapy is an ancient method that
was actually proposed by Hippocrates and developed
in this country by Dr. George Hackett and Dr.
Gustav Hemwel. Both physicians had actively been
promoting prolotherapy for 60 years in their Chicago
based clinic. This method might be used in patients
with severe allergies and patients who don’t
tolerate traditional medications because of side
effects or gastro-intestinal discomfort. Prolotherapy
might be a good adjunctive therapy to intra-articular
steroid shots, non-steroidal anti-inflammatory
medications, and Opioids.
10. Exercise, physical therapy, and gentle
chiropractic manipulations are the valuable
part of comprehensive pain management program.
In the past physicians recommended long term rest
after an acute onset of back pain, recent literature
does not support the advantages of prolonged rest
(18). Today we recommend bed rest for no more
than 2-3 days after acute pain onset that should
followed by early mobilization and activity “as
tolerated”. Prolonged rest may cause more
muscle and joint stiffness and eventually will
cause weak muscles, decreased mobility and increased
pain. Proper exercise performed on a daily basis
is essential for a healthy spine. Exercise, done
carefully and regularly, helps build and preserve
muscle strength, keeps joints and ligaments flexible
and protects them from further damage. Certain
exercises such as the McKenzie exercise program
(extension exercises) are helpful for radicular
pain. Gentle stretching, range of motion, back
muscle strengthening, and posture training are
typical exercise programs we use. These exercises
strengthen the muscles supporting the spine and
around the joints and reduce wear and tear. These
exercises will be taught by our physical therapists
and chiropractors. Initially, they should be supervised,
but later on the patients will be able to continue
their exercise program at home. The patient should
be asked you to keep a log showing the regimen,
intensity, and frequency of a home exercise program
(18).
Chiropractors apply gentle chiropractic
manipulations in order to restore and maintain the
range of motion in the small joints in the spine.
They pay special attention to trunk stabilization
and general conditioning. Misalignments occur in
small facet joints in the cervical spine and lumbar
spine after motor vehicle accidents. Chiropractic
manipulations are helpful to align these joints.
11. Accupuncture and other modalities.
Depending on the patient’s preference, acupuncture,
heat or ice can be used for different types of
pain. Ice or heat is typically applied 3-4 times
a day for 10-15 minutes. Why one person feels
better with heat and another feels better with
ice is not clear, but this treatment can bring
pain relief and some reduction of inflammation.
Heat can be applied in many forms including warm
packs, showers, infrared lamps, and whirlpool.
Cold therapy utilizes ice packs, frozen bags of
peas and corn or a wet towel that has been placed
in a freezer. Different ultrasound devices, microwave
machines, diathermy and infrared lasers might
be used. It is prudent to have different providers
in the clinic with expertise in alternative medicine,
acupuncture, herbal medicine, and biofeedback,
and massage therapy, hypnotherapy and relaxation
technique (19, 20).
12. Prosthetics/orthotics, assistive
devices for ambulation. Orthotics and
cervical and lumbo-sacral braces can help support
the spine and decrease muscle spasms and disk
pressure. Special vendors can assist in choosing
the correct orthotics for mechanical support of
the spine. Temporary use of crutches, canes, rollator
walkers, cart walkers or a wheelchair may be helpful
for some patients.
13. Weight management. It is
crucial to maintain a healthy weight while taking
care of patients with neck and low back pain and
arthritic spine joints. International research
demonstrated that weight reduction could significantly
decrease the impact on an impaired spine (21).
This is an important part of comprehensive pain
management program and includes a combination
of a healthy diet and aerobic exercises for weight
reduction and healthy weight maintenance. Pain
management specialists and primary care providers
should collaborate with specialists in obesity
management, with exercise physiologist proficient
in metabolic testing. The goal of weight management
program is to accelerate basic metabolic rate
and to burn fat tissue.
There are several medications FDA approved for
weight control like Xenical, Meridia, and they
require evaluation and follow up of physicians
specializing in weight management and metabolic
disorders treatment. Patients might be interested
in holistic approach: herbal food supplements,
acupuncture, glyconutrients for appetite control
and metabolism enhancement, body wrapping and
mesotherapy for body contouring (22).
14. Multidisciplinary Chronic Pain Program:
It is important to develop multidisciplinary chronic
pain programs for individuals who failed all other
types of treatment. Pain affects these patients
physically, psychologically, and socially. The
goal of multidisciplinary chronic pain program
is to educate the patient about pain, physiology
and anatomy; improve coping skills, aerobic conditioning,
endurance, strength, treat depression and other
underlying medical conditions, eliminate inappropriate
medications, initiate appropriate medications
and assist patient in establishing realistic goals
and maintain treatment goals. Behavioral health
is a crucial part of the chronic pain program.
Clinical psychologists are experts closely involved
in the chronic pain program to help the patient
to improve coping and treatment of underlying
depression, sleep disorders, anxiety, and post
traumatic stress disorders. Research supports
there is close relation between perception of
pain, depression, sleep disorder, anxiety and
post traumatic stress disorder. It is essential
to treat these conditions in order to achieve
better pain control (23).
15. Finally, about orthopedic surgery.
Primary care physicians and pain specialists are
doing all their best to design treatment and rehabilitation
program for patients suffering from acute and
chronic back pain. Unfortunately, in some patients
conservative management fails, and in those cases
surgical treatment is necessary.
There are conditions that need immediate attention
and surgical intervention in order to prevent
further neurological damage: progressive weakness,
lose of bowel or bladder control, gait abnormalities,
loss of sensation and severe pain.
In those cases the patient should be referred
to an orthopedic surgeon for consultation and
possible surgery, and pre- and post surgical rehabilitative
program should be well planned in advance (22).
We believe that this brief overview of comprehensive
pain management program will allow primary care
providers; patients and non-pain specialists in
general understanding of multifaceted pain management
and different options available on the market.
