Clinical Information

  • A disorder characterized by the sensation of marked discomfort, distress or agony.
  • An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons.
  • Causing physical or psychological misery, pain or distress.
  • Intensely discomforting, distressful, or agonizing sensation associated with trauma or disease, with well-defined location, character, and timing.
  • Pain is a feeling triggered in the nervous system. Pain may be sharp or dull. It may come and go, or it may be constant. You may feel pain in one area of your body, such as your back, abdomen or chest or you may feel pain all over, such as when your muscles ache from the flu. Pain can be helpful in diagnosing a problem. Without pain, you might seriously hurt yourself without knowing it, or you might not realize you have a medical problem that needs treatment. Once you take care of the problem, pain usually goes away. However, sometimes pain goes on for weeks, months or even years. This is called chronic pain. Sometimes chronic pain is due to an ongoing cause, such as cancer or arthritis. Sometimes the cause is unknown. Fortunately, there are many ways to treat pain. Treatment varies depending on the cause of pain. pain relievers, acupuncture and sometimes surgery are helpful.
