Pain and its physical and psychological aspects

Pain is a sensation that can range from mild discomfort to an unbearable and
excruciating experience, with emotional response to that sensation. Pain is a
personal experience and unique to each individual. Pain mechanism exists to
provide a useful warning of possible injury or something wrong in early stages of
various disorders. It may caution against repeating an action that has led to injury,
or conduct doctors to find out some root causes, but it possibly could be useless
for many patients in late stages of some disorders.

The skin contains many specialized nerve endings (nociceptors). Stimulation of
these receptors leads to transmission of pain messages to the brain via spinal
cord. Pain receptors are also present in structures such as blood vessels and
tendons. Most internal organs have few, if any, nociceptors. The large intestine, for
example, can be cut without causing any pain. It does, however, have nociceptors
that respond to stretching, which, in severe cases, may cause pain. If the pain
comes from an internal organ it is often difficult for the sufferer to pinpoint its origin
with any precision.

Pain may be felt at a point some distance from the disorder. This is called referred
pain. A toothache may be felt in the ear, because the same sensory nerve supplies
both parts. Disorders affecting the knee, such as arthritis, may be felt as pain in the
hip.

Pain is usually associated with distress and anxiety, and sometimes with fear.
People vary tremendously in their pain thresholds (the level at which the pain is felt
and the person feels compelled to act). The pain of cancer, because of fear of the
disease, may seem much greater and cause more suffering than similar pain
resulting from persistent indigestion. Unexplained pain is often worse because of
the anxiety it can cause; once a diagnosis is made and reassurance given, the
pain may be perceived as less severe.

Acupuncture and pain

Many people with chronic pain are finding relief through acupuncture, chiropractic,
hypnosis, massage and other complementary and alternative (CAM) therapies.
According to a recent Stanford University survey, as many as 69 percent of
Americans are using CAM therapies, and many allopathic (conventional) doctors
are incorporating these therapies into their practices. Thirty-four U.S. medical
schools—including Yale and Harvard—now offer courses in alternative medicine,
and in 1999, the National Institutes of Health opened the National Center for
Complementary and Alternative Medicine to evaluate alternative treatments.

  • Why chose acupuncture?

It works for whole person including body level and mind level at same time. Of
conventional and CAM methods, some treat body(physical), some treat mind or
emotions, some treat all of them. For qualified acupuncturists, pain condition is a
problem happened in a whole person’s system. The relationship between pain
location and its background organs (tissues) or meridians (the pathways of energy
flow) is important. Pain and emotion would be better understand in acupuncture
theory then a set of suitable acupoints would be chosen, and the needles would be
operated correctly.    

Acupuncture is a fine medical system with thousands of years’ practicing and
much success, not a simple therapy or treatment method. It includes its basic
theory on human structure with meridians map, which was drawn in a book 2000
years ago  in ancient China, its oriental philosophy, and its practical diagnosis and
treatment strategies.

It is also preventive, by establishing a whole balanced person and educating the
patient so health problems do not occur.

It is safe, gentle without side effect. In the hands of a comprehensively trained
acupuncturist, your safety is assured.

Avoid and reduce huge expensive in conventional medicine.

Recent research showed that more Western-trained doctors believed in the
effectiveness of acupuncture and Chinese herbal medicine than any other
complementary or alternative medicine.   

  • How does acupuncture work for pain?

Meridian system: There are 14 major meridians and their branches network in
human body. Energy flow along the meridians to nourish, support and connect
different part of the body. Pain related to specific meridian means that this meridian
has blockage or stagnation of energy.  Acupuncture needles work to unblock
meridians and make the energy flow freely.   

Gate theory of pain (1965): the theory believe that pain messages travelling along
the nervous system only reach the brain if enough of them reach an imaginary
'gate' and open it. This theory supports that there is a clear pain 'threshold'. As dull
ache-conducting nerve fibres transmit their message relatively slow, the faster-
moving light and firm touch fibres can be activated to beat the pain fibres to the
'gate' and close it behind them. In other words, acupuncture and massage are
ways of blocking out nagging pain.

Modern researches have showed that acupuncture can promote the release of
endorphins and therefore relieve pain.

Researches also showed that acupuncture stimulates reactions including
changes in brain activity, blood chemistry, endocrine functions, blood pressure,
and immune system response. These effects possible make patients feel
stronger and easer to control themselves. Factors such as insomnia, anxiety, and
depression, which often accompany incapacitating illness, lower pain tolerance.
Some acupuncture points are often chosen for treating those conditions at same
time.

Researches from NIH
(National Institute of Health
)

"Acupuncture provides pain relief and improves function for people with
osteoarthritis of the knee and serves as an effective complement to standard care.
This landmark study was funded by the National Center for Complementary and
Alternative Medicine (NCCAM) and the National Institute of Arthritis and
Musculoskeletal and Skin Diseases (NIAMS), both components of the National
Institutes of Health. The findings of the study--the longest and largest randomized,
controlled phase III clinical trial of acupuncture ever conducted--were published in
the December 21, 2004, issue of the Annals of Internal Medicine."...  for more
