Document Summary
Analgesic: relieve pain without significantly disturbing consciousness or altering actions of sensory nerves. Some of these types of drugs also have anti-inflammatory properties. You have to figure out the source of pain, and what kind of pain it is in order to find the best medication. Central nervous system"s reaction to potentially harmful stimuli characterized by physical discomfort. Acute: severe pain with sudden onset; serves as early warning to seek medical help to prevent damage to the body. Chronic: lasting a long time or marked by frequent recurrence. May result from inflammatory process that causes tissue injury. Histamine, prostaglandins, serotonin, and bradykinin are released and initiate action potential along sensory nerve fiber. Nociceptors (pain receptors) are activated and message sent to brain cortex. Appropriate autonomic and reflect responses are activated. Nociceptive pain: include sprains, bone fractures, burns, bumps, bruises, inflammation, obstructions, and myofascial pain.
