(Greek: pain, sense of pain; painful; hurting)
Used actively in medical terminology to denote a condition of sensitivity to pain as specified by the combining root.
Acromelalgia is a condition affecting the extremities, especially the feet, and marked by burning and throbbing sensations that come and go.
The throbbing and burning pain in the skin is often caused by exertion or heat, affecting the hands and feet, accompanied by a dusky mottled redness of the parts with increased skin temperature.
Dental pain is caused either by increased or reduced atmospheric pressure.
2. A neurologic or pharmacologic state in which painful stimuli are so moderated that, though still perceived, they are no longer painful: Dr. Jones, the neurologist, studied the effect of the new medication on the alganesthesia of patients from the combat zone.
Beyond the pleasures and assurances of touch, there is always the looming possibility of pain. As a survival mechanism, pain warns our brains of danger and tells us to act to correct or avoid the cause.
Pain receptors, free nerve endings, are spread over a larger area than any of the other sensory receptors. They completely ignore light contact, and only fire up if the stimuli threaten to damage the tissue.
There are more pain receptors in the skin than other types of skin sensors, but they are not evenly distributed; for example, the neck and eyelids are densely covered, but there are few receptors on the sole of the feet and on the ball of the thumb, which is why the needle prick for a blood sample is often done on the thumb.
Though familiar to us all, pain is mercifully difficult to remember once it has passed (if it were not, it has been observed, every family would have but one child).
Doctors refer to the short-lived suffering of childbirth or surgery or even a toothache as ‘acute pain’; it is terrible at the time, but ultimately it passes.
For untold millions, however, pain does not pass. It sings on through the night, month after month, overwhelming sleep, stifling pleasure, shrinking experience, until there is nothing but pain.
This is chronic pain, and its sufferers are legion: there are more than 36 million arthritics in the U.S.; there are 70 million with agonizing back pain; about 20 million who suffer from blinding migraines; millions more who are racked by diseases like sciatica and gout.
Most feared of all, the pain associated with cancer afflicts some 800,000 Americans and 18 million people world wide.”
Albert Schweitzer once said, "Pain is a more terrible lord of mankind than even death himself."
