  Pain - Wikipedia, the free encyclopedia
Slow pain is transmitted via slower type C fibres to laminae II and III of the dorsa horns, together known as the substantia gelatinosa.
Pain is also "gated" by signals that descend from the brain to the spinal cord to suppress (and in other cases enhance) incoming pain information.
Since pain is defined as a signal of present or impending tissue damage effected by a harmful stimulus, the ability to experience pain or irritation is observable in most multicellular organisms.

 Pain Control
But pain is also modified by remembrances of past painful episodes, the special meaning of pain to each individual, the expectations of family and friends, religious upbringing and personal coping skills and strategies.
Pain from bone involvement is often described as achy, dull, localized and brought about by activity of the surrounding muscle groups or movement of the limb or spine.
Neuropathic Pain from nerve involvement is either related to direct tumor spread, such as the spread of colon cancer into the pelvis where the nerves to the legs or pelvic structures reside, or is secondary to irritating substances that tumors secrete near nerves.

 THE MERCK MANUAL, Sec. 14, Ch. 167, Pain
Acute pain, an essential biologic signal of the potential for or the extent of injury, is pain that lasts or is anticipated to last a short time, typically < 1 mo. It is often associated with anxiety and with hyperactivity of the sympathetic nervous system (eg, tachycardia, increased respiratory rate and BP, diaphoresis, dilated pupils).
Chronic pain is usually defined broadly and arbitrarily as pain persisting > 1 mo beyond the resolution of an acute tissue injury, pain persisting or recurring for > 3 mo, or pain associated with tissue injury that is expected to continue or progress.
Similarly, pain and suffering should be distinguished, especially in a cancer patient, whose suffering may be due as much to loss of function and fear of impending death as to pain.

 Pain - OncologyChannel.com
Pain is the result of a physiological series of electrical and chemical events that occur in the body.
Pain receptors are bare nerve endings that are widely distributed throughout the body in the skin and mucous membranes.
When pain receptors are triggered by mechanical, chemical, or thermal stimuli, the pain signal is transmitted through the nerves to the spinal cord and then to the brain.

 Click2Houston.com - Health Encyclopedia - Nonspecific Back Pain
Back pain can develop in association with a number of causes, including muscle strain, injury to the back, overuse, muscle disorders, pressure on a nerve root, poor posture, and many others.
A physical examination focused on the back, the abdomen, and the extremities may confirm back pain or muscle spasm, but the examination does not reveal a specific cause (such as a herniated disk) or any neurological problem (such as weakness or change in sensation).
This is particularly important if the pain travels down the legs below the knee (suggesting pressure on the nerves as they leave the spinal cord), or if there is weakness or numbness in a leg.

Pain in younger patients also requires special attention, particularly because young children are not always able to describe the degree of pain they are experiencing.
Pain is a complicated process that involves an intricate interplay between a number of important chemicals found naturally in the brain and spinal cord.
The idea of using receptors as gateways for pain drugs is a novel idea, supported by experiments involving substance P. Investigators have been able to isolate a tiny population of neurons, located in the spinal cord, that together form a major portion of the pathway responsible for carrying persistent pain signals to the brain.

Pain is a perception, and like any perception, it is rooted in sensation, and on the biological level, in the stimulation of receptor neurons.
Referred pain, such as the pain that people sometimes feel in their arms and shoulders when they are having a heart attach, is due to the way in which nerves come together in the spinal cord.
Phantom pain -- the pain amputees sometimes feel in the very limb they are missing -- is due to the fact that, when nociceptors are damaged or missing, the neurons in the spinal cord that transmit pain messages sometimes become hyperactive.

 International Association for the Study of Pain - Pain Terminology
For pain evoked by stimuli that usually are not painful, the term allodynia is preferred, while hyperalgesia is more appropriately used for cases with an increased response at a normal threshold, or at an increased threshold, e.g., in patients with neuropathy.
The stimulus is not pain (q.v.) and cannot be a measure of pain.
Thus, the same argument applies to pain tolerance level as to pain threshold, and it is not defined in terms of the external stimulation as such.

Pain is the body's way of sounding an alarm that something is wrong.  Some people think that pain is a natural part of aging or illness.
Pain is most often associated with physical pain but chronic or ongoing pain can lead to emotional suffering as well.  In addition to physical discomfort, chronic pain can lead to sleep problems, depression and disability if your pain is not treated.  You also may feel overwhelmed by intense emotions of panic, grief or anger.
Chronic pain is frustrating to live with, both for you and for the people near you.  Because chronic pain is such a personal experience, it's difficult for anyone else to understand exactly what you're feeling and going through since no one knows your pain like you.

 Chronic Pain Information Page: National Institute of Neurological Disorders and Stroke (NINDS)
While acute pain is a normal sensation triggered in the nervous system to alert you to possible injury and the need to take care of yourself, chronic pain is different.
Common chronic pain complaints include headache, low back pain, cancer pain, arthritis pain, neurogenic pain (pain resulting from damage to the peripheral nerves or to the central nervous system itself), psychogenic pain (pain not due to past disease or injury or any visible sign of damage inside or outside the nervous system).
Many people with chronic pain can be helped if they understand all the causes of pain and the many and varied steps that can be taken to undo what chronic pain has done.
